Looking for used original body mounts 70-72

I must be out of my mind but I am going to look into having correct body mounts made for my car and to sell. I will hopefully have my 71 Stage-1 engine sticker finished now that Christmas has gone by. As anyone who has looked into this knows the reproduction body mounts out there are pieces of crap. The only exception are Cars cushions with the washer molded in that are very close to the GM originals. There core support mounts are also pretty good but they are too wide and maybe a little too thick as I had the fan hitting the lower part of the shroud when I installed them.

There are 4 types of mounts used on a 70-72 GS(3 on a skylark)
1) core support mount also used on 4 areas below trunk floor(also under firewall on Skylark only.
2)Under Firewall. These four mounts have violet paint on GS only and are wider than core support mounts
3)Under doors. These ones are the widest and most unique.
4) above differential area. These four are the plug in type.

I have my originals but they are flattened out pretty good. I need one good original of each that is not too badly rotted or flattened so I can get proper measurements and take to a local rubber company. I can return them if you wish.

I will do a real comparison soon with pictures I hope to show the difference. I am tired of the restoration industry not making anything correct for Buicks except for a few key guys here on this site so if the price is not too high and I can get my money back then maybe it is worth it. I maybe able to get an Olds friend to help with financing if I find this stuff crosses over.

Let me know if there is any interest or if I am wasting my time and will just get stuck using the hard hockey pucks everyone else uses.

I can send check for shipping on the used mounts no problem.

 

I wish i could help but i could bump.!!!

 

Let me see what I have .

 

Thanks that would be great.

 

Just a thought. What did JW use on Jim Lore''s cars after the resto.

 

Dave,
OK, I gotta ask, why do you want used originals as they would be flattened and distorted from years of use?

Also, which type of bushings are you interested in reproducing. The early 1970 cars had different ones then the late 70-thru-72 cars, plus the oldsmobiles were shaped totally differently. Then you need to deal with the different "durometers" (rubber hardness) for different applications, and the fact that some of our Buicks originally came with "Chevrolet" cast right into the bushings. (So at least some of the assembly plants obviously used other brand bushings.)

I am not trying to criticise, just trying to understand where you are coming from.

Thanks for that info Duane I was hoping someone would speak up with some rubber experiance as I know you have molded some parts. I would be interested most with the mounts for the later 70-72 cars as I would bet these were the most popular. I was not aware early 70's used different mounts. I know mine are pressed down somewhat so I would just like to find out what original thicknesses of the mounts were and if this is even feasible to pursue. Maybe the tooling costs would be way too high as well. My main concern is finding the correct thickness for body height and mounts that are not hard as a rock.

 

Dave,
I guess I'm loosing the point here, I have used the reproduction mounts that Poston sells many times and they worked fine. (I always used the new bushings along with the original bolts/hardware.) Now I could see wanting to use the original "square" Olds core support bushings because they have such a different appearance, but other then that....

Besides, once you paint the majority of your mounts yellow you can hardly see the differences.

Duane, I have not tried Postons but have purchased 3 sets from other vendors and found that the cushions were junk and did not have the washer molded in like the ones Cars sells individually.. Also in the sets the mounts themselves were smaller in diameter or in other kits the bigger mounts were rock hard. I thought they would make car like riding on solid body mounts. I just did not want to purchase another set if this is already what I had. I checked Postons sets on their site and they have one with hardware and one without. I noticed that the mounts themselves looked different in both sets?

They also dont appear to know that Buicks used the set with extra mounts under the firewall as they offer hardtop and covert sets. in the past I ordered hardtop set and was short two mounts. Also how is density on there mounts?

 

Just for clarification I use the word "mount" for the piece that is between body and frame and "cushion" for the rubber piece with washer molded in the goes under the frame and bolt goes up through it.

 

Dave,
I purchased my Poston body bushing kits years ago, and at the time they only had sets that included the hardware, so I reused my hardware and tossed theirs. (There was nothing wrong with their hardware, I just wanted to use the original pieces.)

I liked these kits because they included the double set at the firewall as well as the core support bushings for about the same price as everyone else sold the regular sets. Plus it was easier for me to order it all in a single package.

These sets may have been smaller in diameter (not sure on that one), but they did have the washer molded into the insulators like the original buick mounts had. (The Oldsmobiles came with the other style, basically the insulators were a rubber ring with a loose washer and bolt.) These are the pieces you are calling "cushions".

Today they are probably packaged as Chevelles so you get the Hardtop/Coupe vs Convertible designations. For Chevelles the hardtops used 1 body mount at the firewall, while the converts had 2 on each side. So if you ordered the conv style you would end up with the correct set for a Buick coupe/conv.

As far as the ride/feel, I have a set under the X-Camino now and have no trouble with it, the car has a nice ride and feels good and solid. I and my friends have installed these sets on A-body Buicks, Chevies, and Oldsmobiles, and all appeared fine.

I can't give you more info then this.
Duane

PS. All the dam* things do is hold the body to the frame. As long as they do their job I don't see why there is a fuss about them. Plus, again if you want to do Concours you are painting the insulators yellow, so you can hardly see the differences.

PSS. Maybe I should look at one of the sets you bought where the insulators do not have the washers molded in. They might be like the originals on my Olds, and I could use a set.

 

Duane....since you brought it up, what is the 'correct' way to paint the insulators?:bla:
....I've seen both spray painted, and ones that look like they were done with a paint stick. Were both methods used?

 

Walt,
I have seen originals that ranged from having only a thin swipe of color part way around the bushing (like it was put on with a small brush) to ones that look like they were dipped in a paint bucket.

Your choice.:laugh:
Duane

 

spray bomb?

 

Duane, I will get some pictures out to you of the extras I have. Maybe I can come up with a complete set with what you need. Maybe I could trade for a set of Underhood insulation or something.

As for the painting of the cushions my originals looked sprayed yellow. The under firewall violet painted mounts looked like someone used a brush and turned the mount in a cirlce to paint. This is on my 71 anyway.

 

Dave, you probably already know about these sources for replacement body cushions.... but in case you missed one:
http://www.oldcarstuff.com/
www.restorationspecialties.com
www.steelerubber.com

oldcarstuff has some nice ones. They seem to be going after the resto crowd. maybe they would be interested in your project. BTW, that co also goes by CARS, who most of know of.
While you're at it, how about some repos for our older GS's?:TU:

 

Thanks I know those sources. I actually have tried Old Cars BM644 under the firewall area and I just took one out tonight to check it and it looks like it compressed about 1/2". Not sure if that is to good. I guess most weight is in this area. They have only been in two years. Their cushion BM644A is replacment for GM Cushion#1377367 and it is very good match however. I guess my car is (was) a rolling test bed for mounts.

 

These are original bolt on body mounts used on later 70 to 72 GS only. Left mount is used at core support and 4 areas under trunk. Middle mount is used under firewall on GS only. You can still see brush painted violet paint that ius very faded. The last mount is used under doors only it has a smaller 9/16" hole wher the others used a 3/4" hole.

 

These are differnt styles of reproductions. The only type with correct size 3/4" or 9/16" holes are much smaller in diameter. The correct diamter types have enormous 1" holes and shorter metal stemms that do not extend through frame all the way. I think this may cause the cushions to "walk" under hard turns.

 

These are correct type cushions The first(left) is an original installed 71 Gm type with molde in washer and ridges on side with factory yellow paint. The middle is(was) a GM NOS with part number stamped om bottom and it has no ridges. The far right is a CARS repro that is identical to the GM NOS and painted yellow by me. They are sold seperately and expensive ast about $7.00 a piece. They are the only one worth using in my opinion.
