I have a 69 pace car and the sub frame rubber is squashed flat. I have had the suspension replaced (tie rods and rubber), new shocks and tires. I still have a "body shake" at 38 to 42 miles per hour then it quits. It only shakes at 40 mph. The entire is factory correct and matching (no modifications). I have purchased a GM gromet set and hardware. It looks impossible for me to do. Any suggestions as to where to take it? Body shop or ??
I'm in Southern Mississippississippi. phew!

Start with the easy stuff first. I'd get the tires balanced on a Hunter GSP 9700 tire balancer. Follow this link to read more about their force balancing and locate one near you:

Their balancing is lightyears beyond the old way and will give you smooth-as-silk cruising!! It's really sweet! If that doesn't take care of the vibration, then I'd look into the subframe bushings and rear end, etc. Good luck!

Edit: another thought: do you still have the convertible shakers in your car? That can cause vibration problems if they're missing.
