'68 318 to carbed Magnum 5.2: Check my checklist
L9oks great Kurt. I'm a bit surprised you are going with the Sanden after all that work to keep it stock-ish looking!
Well, given that I'm down here in South Florida, I rather like the idea of reliable R134a. That, and I swore off converted compressors after foolishly beating my head against countless Delco A6s in a pair of '70s Lincolns I had (prior to the Chinese aluminum drop-in units). Granted, the A6 is the worst offender (and one of the many things that puts me off GM), but still.
The RV2 that came from the car was a 1980's unit with questionable history, so using it wasn't necessarily the best idea either. Believe me, I'd jump on a modern drop-in RV2 replacement, but it's not as if such a thing exists.
I will say this though: The Sanden is getting it's label ripped off and the housing painted black. Heck, if I can find a reproduction Mopar label for an RV2, I'll stick it right on the housing.

P.S.: Be careful doing the rear seal on your Valiant's engine. Easy to tear it between the crank and the block. Not difficult though, given some finesse. You might find a rope seal back there; can't recall what my '68 block had.
