64Corvette

Mine is a 64 and I do not have holes on either sides of the frame to insert a cotter key through the shims to keep them in place. How do I keep from loosing the shims again? Thanks

Any pictures where to drill a hole through the frame?

Dont put slotted shims in and they wint fall out.

Chuck Gongloff

Use the correct 2 hole shims. OR

Drill a hole through the frame for the 6"--8" cotter pin used in 69 and up Corvettes to retain the slotted shims. OR

Get the double hole shims and modify them with a notch on one end so the shim will slide over the bolt.

Modified 2 hole shims from a previous CF thread.

Have you or someone replaced the bushings at the front of the trailing arms?

Not having a slot in the shim is a lot of work to remove or replace. What I did was, rotate the shims where they fit just inside the opening leaving a little of the shims end outside. This kept them wedged in and from sliding out.

Yes, they have been replaced.

This pic is from a '69, but this is where the factory hole is.

If the new bushings were not installed and compressed properly, replacing the shims will not cure the problem. They will always be loose. Even the angle slotted shims will work loose. Read about this at the link below.

Use the slotted shims for ease of installation. Fit the shims down in the T/A frame pocket to keep from backing off and falling out. Drill through both sides if frame to install long cotter pin or long black tie-wrap to secure shims.
