Recommendation for rubber subframe and core support bushings
« on: September 14, 2019, 03:45:29 PM »
68 base coupe. 
Iíve read the many threads on rubber vs poly vs solid bushings.  I want to replace with rubber but having trouble finding source which looks ok. Iím not looking for perfect originality- just OEM looking type bushings. Iíd appreciate any experience & advice on sources.
Thanks
Ed

As John Hinckley always says, the original rubber lasted 50 years so chances are the next time they'll need to be replaced, you'll be dead! Use rubber. Most vendors sell them. HERE'S Classic Industries. Heck, even ROCK AUTO has them!

I went with GM Restoration. Body and suspension. However,have you just looked at Moog?

I decided on polys for the engine mounts. Summit's were spot on,dimension wise, of my old Anchors. And black. Rubber trans mount.

As I read on other site's posts, and now agree, was not happy with Anchor's interlocked mount for pre 69. I think they also get packaged under Lakewood Muscle Car. Interlocked design, but poor, and cheaply made,,,as I read. My old Anchors are oe design, thick plates, but non-interlocking. Maybe for the shows, not using on the street. Staying shelved unless I need them. I actually ran solids for years, but different direction with the car now, not needed.

Thanks for responses. Yeah, Iím just planning on cruising around so i want to use rubber.  As you said, after Iím gone if my son wants to change them - he can!
Iím sorry I was confusing in my question. I was curious if anyone has recent experience with rubber brands - good or bad. 
I saw ďgoodmarkĒ on rockauto but not sure what they are and rep. It doesnít actually say what material they are which seems kind of lame.  I got OER for a core support years ago and thought them kind of cheap looking but perhaps that is just they way they are. Iíve never seen new or NOS bushings. I looked on Moog but they appear to just have suspension parts.  So all Iíve found are the goodmark and OER so far.

You might try Classic Headquarters (CHQ) too, many of their reproduction parts are pretty good from a quality and fitment aspect. I'm striving to keep as much of my car GM as possible, but for body and drivetrain mounts - far happier with the best reproduction I can get than trusting originals or decades-old NOS......

The nicest set I bought were the CHQ parts, they looked exactly like the NOS ones, (metal inserts etc) except no GM part numbers or wording on them.

My set is going on 40 years old - started buying them in about 1980. The comment about lasting 50 years is likely close; these look like brand new, shame I didn't think to buy more than one set when I had the chance (some of these cost just a couple of bucks apiece, new). My point for picturing them is the reason I always like to use GM OEM when I can - part numbers and manufacturer are usually cast right in, made in the good 'ole U.S. of A. Hard to beat them -

I think I've got all of them, including jounce bumpers and rebounds if anyone needs detail pics -

Gary,

I thought about that before I posted the pics - although I (very stupidly) sold a good many parts over the years, I realized I couldn't replace what I sold, so I quit selling the ones I needed for my car(s), and concentrated on finding what I needed without losing any more important and irreplaceable parts. Man, I really wish I had a lot of things back -

I had one car, my X77, from 1973 until 1992 and the arrival of my LS5 '70 in the garage, so everything I bought to that point was a reserve just for the Z. Then the others showed up (the Chevelle had to go) and the expansion began. Idiotic not to buy a whole basket of bushings for $2.40 apiece when I could; same goes for $278.00 quarter panels and $228.00 front fenders. Hindsight is always 20-20.

I offer the pics for reference - only until they get assembled !

Regards,
Steve

Thanks for replies.  I checked the GM restoration parts on CHQ and they look nice.  Iíll try them. I bought OER core support bushings years ago and the OD of the rubber was much smaller on the top rubber and the bolts looked like bolts you could buy at ACE hardware. So I just replaced the one side that was perished. I want to do all the bushings now as Iím doing some front end work. I donít know if they are the same now, of course, but since itís not something I want to do again Iíd like to try something better.
Thanks for help
