Refinished and installed the f & r moldings. I switched out the short aftermarket greenish plastic clips I used in the front with original metal ones I cleaned up. Everything snapped right into place and fits well. The reproduction moldings will be going in the trash where they belong.
Seats turned out well. The car originally came with custom cloth, but my son preferred the custom vinyl. The rears still need some adjustment but not bad given that the upholsterer didn't have the car and had to rely on my measurements. I didn't modify the rear panels, and although they fit over the mini-tubs, they're not quite vertical either (wider at the top than the bottom) and so we had to deal with that when modifying the rear seat back covers.
I hope to have some time to make significant progress on the remaining wiring this weekend. The plan is to have the car ready for start-up in a two weeks when my son is home for spring break.
