Body Mount Torque Specs
Does anyone know the proper torque specs for polyurethane body mounts on a 1980 corvette? I can't find it anywhere. I have my assembly manual for a 69 Olds Cutlass that says its 50ft-lbs, but thats a completely different car. I would appreciate any help thanks.

center of the poly mounts. The bolt clamps down on the spacer, not
the cushions. Check it out - and see what I mean. The cushions are
only compressed as far as the spacer. Use normal torque for that bolt
diameter ... 7/16" coarse I think.
I don't have a picture of the spacer, but here is a mount that is torqued
down for reference:

For the #1s you can go full torque for grade 8 (assuming you are using
grade 8). However, I'm not confident that the stock cage nuts are very
hard, so I'd limit the cage nut mounts to 50 ftlb max.
Ah-hah: Just found it in my 75 AIM ... section 1B pg 2: 40-50 FTLBs.
