I had to address the door bumpers for the 330GT restoration. The old ones were rock hard and needed replacing.

The new ones leave a lot to be desired. The have the general shape, are made out of rubber, but that’s about where it stops as a reproduction. They’re thicker, and missing the brass bushings inside to keep the retaining screws from bottoming out. These were not simple bolt on pieces!

I pressed out the original bushings in the original bumpers and inspected their design. I was missing a couple of bumpers on this car, so I had to make some replacements from scratch.

I pressed the new bushings in place after sanding the rubber bumper down to the proper thickness.

Before installing them on the car, I chased the threads on the nuts to clean out the paint left by the painters.
