Maybe that is one of those later build items or what was commonly done, if one parts bin was empty they grabbed whatever was available. But the options for the smaller diameter are INL12795 (listed for the Pontiac, purple color) or INL12643 (Chevy, black). I know my originals in the rear (I don't recall them being smaller) had a metal exterior sleeve that nobody reproduces but I used the common flat top with no issues (INL12477)
I have the Parts Numbers needed. I just need to get the items ordered, received and placed into "Kit Form". It will be a couple weeks but it's in the works . . . . . The next kit I put together will consist of this: Inline Tube Bushings (3 different ones as discussed here) CARS Bottom Bushings with Molded in Washers AMK Bolts (Both lengths) Not sure on pricing yet but it won't be more than these companies Retail Prices. 3 Different Companies will be involved in getting this Kit to market! I may do another one with Core Support Bushings also included.
Yes exactly what a lot of people need. I already spent to much on wrong or poorly fitting parts I'd rather spend more for a quality item that is approved and fits!
Yes we maybe worry way to much about stuff the factory workers couldn't care less about in those days
Yes this one...looks like a decent kit for a driver and price/performance wise. Has molded in washers. Asked them if they ship USPS...they don't so I cannot buy from them...shipping is more than the part itself. but looks like it misses the shorter bolts for under the doors...
I think the 12642 matches the original better. I purchased both the 12642 and the 12476 and the 12642 matched better. Also the 12476 has a larger hole. I have added a picture of the originals. I think my car had all 1383301 except the one under the door. The ones looked wider but the two I have are the same part number., I will have to check the rest. .
This is the original with the 12476, it is also thicker rubber. I do not have a side by side picture of the 12642 as I already installed it. When I compared them all side by side I thought the 12642 was a better fit and thickness. .
Nelson- thanks for the pictures. 1. From this, who has the most correct replacement for the lower body mount #1377367 with embedded metal washer? 2. Who has the correct (or close to correct) metal sleeved bushing? 3. Who make the correct, non bolted rubber bushing (position 4 and 5)?
I would like to do the body bushing and replace with the correct washered bushings. I agree the rear most are thin. I had done them on a couple cars as the bottom part would be gone and a washer hanging on the bolt. This is a great winter project.
Which are the most correct. And are any more parts needed? Thanks for sharing. This is a much bigger thing since I did these in 80s-90s.
I purchased the one in the picture 12476 from inline tube. Both 12476 and 12642 were purchased from inline tube. You can see in the picture it has CARS BM-644 molded into it. I do not know who manufactured it, all I know is who I purchased it from and what I see molded into it. .
it is obviously the CARS upper part. So general conclusion is Inline Tube upper bushing, separate one for under the doors and the CARS lower part along with those AMK hardware. All we have to to is wait for Todd to post the new "correct body bushing set"
I'll be pulling my 70 Stage 1 Body off it's Frame in the next week or two. Once I have my Factory Bushings in hand to compare to I'll be ordering in a bunch of bushings and will in the end hopefully be able to decipher all this info and put together what will become the Best-Most Correct (At this time) Body Bushing Kit for our Buick's. Stay tuned . . . . . Bolt Kits are already available and in stock. Pretty much just need to get this Bushing thing figured out!
Looks like I got a few body mounts with one of the projects. These are rubber, have somewhat correct inserts. The washers are vulcanized into the rubber correctly.. The code stamped into the rubber is BM003. I compared them to the originals I had...
Update 11-18 As of today all the Bushings are on order from Inline Tube and CARS. (The correct Bolts are already in stock) Providing they can fill my order I should have these kits available sometime next week. I'll post photos once they're all set to go. I'll offer 2 Kits . . . 1) with Bolts and 1) without Bolts.
Note for anyone planning to buy Inline Tube mounts. To my surprise and disappointment, the Inline Tube cushions are only the top half (the big cushion). They do not include the bottom cushion section. I went back and looked at the description and it doesn't claim to give you both peices nor a washer. So just be aware that you would have to buy the bottoms separately.
Sounds like the preferred Bottom Washer is the CARS version. (Molded in Washers like the originals) I have a BUNCH on order as we speak which should be here sometime next week. My Kits will consist of Inline Tube Tops and CARS bottoms. (and AMK Bolts) .
