Hey guys, I'm not finding the bushings I need for my 67 Lark. Does anyone make replacement bushings that are the same size as OEM? Everything I've found will work but is much smaller in diameter.
The ones cars sells are bigger in diameter. BM644 and BM644A for cusion. These are based on the later type NOS mounts. They are wider than most I have seen. Cars site is www.oldbuickparts.com
Take a note here too. They wont be smaller diameter for long. Once they are tightened they get larger
The packaging should tell you for sure but I think its like 60-75 lbs Look in the packing paper it will have the layout for the frame and the torque specs
On my 72 it's 40-55 lbs. Probably about the same on yours. BTW replacing body bushing was a real PIA. Art RTR
The generic kits have most of the bushings you need, the smaller diameter ones are correct for several locations. As mentioned, you can get the larger diameter ones for behind the axle, and the puck-style (no tru-bolt) from the oldcarstuff site. I bought the generic kit from GroundUp, www.ss396.com ,which included a nice bolt set.:TU:
None of them are exactly like the installed on assembly line units. All reproductions are much harder than original. The Cars BM 644 are the only ones that have metal molded right into the rubber at the top like the originals. I am not talking about the tube insert but molded in steel. I have not idea why it is there. It is not on Oldsmobiles etc. I guess you got more when you paid for a Buick. Also the Cars BM 644 A cushinons have the molded in washers like original They are far superior to ones without washers. They are needed because the cushions really flatten oot when torqued to 55 lb. Much more than that and they will be flatttened.
Most of the kits I see have generic gold hardware store bolts. You can get the correct style from AMK. Because the newer mounts compress less you will need some of the shorter and some of the longer bolts.
Be aware the 64-67 mounts are 3/4" thick. Later cars are 1"+. pn's posted above may not work properly on your '67. I still recommend the DC-1515 kit from Ground Up. http://www.ss396.com/mm5/merchant.mvc?Screen=PROD&Store_Code=chevellecamino&Product_Code=DCC-1515 It comes with flanged bolts, not the hardware-store bolts like Year One. If you do want a perfect bolt set, get it from AMK. There are 2 mounts over the rear axle that do not use thru-bolts. www.restorationspecialties.com offers a #20024 that is correct. The BM-11 from CARS is a little bigger and thicker. Mounts behind the rear wheel are a larger diameter than the ones in the kit. You can buy the larger ones from Restoration Specialties. I don't recall the pn.
Walt, What about the core support bushings do the chevelle ones work also? I'm getting ready to do the wife's 66 Skylark. Thanks, Alan
Chevelle core support bushings are different. I once had a set but returned them as they weren't usable. Believe they were smaller diameter and too tall I finally bought some at a swap meet from Restoration specialties, but had to drill out the ID with a hole saw. Sorry, but I don't have a pn for them.
