I was surprised, Geez Louise!
Better we discovered these crap parts now, it’ll be an easy fix with some new solid polyurethane bump stops. I'll also take the opportunity to change out those too-short steering bolts mentioned earlier.
While waiting for the new bump stops it’s time to start narrowing the back seat for our mini tubs. I started with the backseat bottom by pulling back enough of the new cover (see note) to expose the frame. After marking it, and placing a wet towel it was time to start cutting. So far so good, haven’t ruined the cover or caught it on fire!
Note: One of the first things I did after purchasing the original Camaro (it came with a complete deluxe interior kit) was to have the seats reupholstered. This was well before the new mini-tubed Real Deal Steel body was a reality.
