For those with a 67 Grande or GP, it's a well known fact that the setup gets plagued with rattles when the shaft bushings break and fall out. Even when new, I don't think it was a very well designed setup, and new bushings are hard to find. When you lose the bushings, the lift bar shakes and bounces around so much that the plastic doors will eventually break at the tabs.

In an effort to improve on the failed bushings, I found that 1/2" Pex waterpipe fits over the shaft. I slid 4 cut sections on, and retained them with pieces of 3/16 hard rubber sheet punched and cut to fit the OD of the pex. Used self drilling Tek screws to retain the rubber. The shaft turns smoothly inside the Pex, has zero play and in the end is actually now rubber mounted. Purists won't like the crude Tek screw approach, but it works and really isn't seen.

On the door stop bolts: I used sections of silicone plug wire boots to replace the failed bushings. Give a much softer cushion stop for the doors, and should eliminate any rattles.

On the broken door tabs: I carefully epoxied the remains of the 3 broken tabs back on minus the speed retainers. I then made up small curved strips of aluminum with holes punched, and applied them to the flanges with epoxy, installed the speed clips, than painted it black.

Should provide a little more life to the doors as they were scattered with small random cracks all along those flanges.

I also repaired 2 broken upper grille mounting tabs with epoxy soaked cloth sections. I could have went all out and completely restored everything, but I'm just not into doing that anymore.

Also took the time to line up the doors (a must) with the grille sections. Looks better. Worth the effort.

Hopefully this might give some 67 GP guys some ideas should (when) they encounter the same issues.

Hope your summer is going well, Cheers, Mark
