A few more details… I brush-painted the trunk bolts with hugger orange touch-up paint from Mahopac, after a layer of black primer, done two at a time off the car so as to not realign the trunk, then final touch-up on the car after wrenched down.
I sourced a pair of restored Wittek upper radiator hose clamps. The dates are not correct, but I am amazed how much nicer originals are than the thin, fragile, and frankly BS reproductions. My brand new reproductions bought at various well-regarded suppliers are now forcefully jettisoned into the recycle bin. As many of you know, the repros can fail catastrophically, and in my small sample size maybe half of brand new repros go on just slightly crooked and become junk immediately. Maybe this is obvious but originals are so much stronger, and easy to use. I was close to just switching to modern clamps for peace of mind, but these originals are fantastic (and look great too)
New repro alternator belt from Quanta, B-442 or GM 3932438 which is for a small block automatic w/ AC and also the right length for a desmogged Z. Puts the adjuster bolt right in the middle of the slot.
Restored air cleaner wingnut with repro stud - correct black nut for cowl hood instead of the chrome finish nut that would match a chrome air cleaner. I also removed the rear side marker exterior gaskets - looks a lot sharper with that polished bezel directly against the hugger orange. I guess those GM designers knew what they were doing…
Cleaned up, tuned up, and ready to rock!
