I assumed you were going to have someone do the work for you (that's what I get for thinking!) What I've done in the past is mock up the system with an old compressor, replacing all other parts needed, then replace the compressor near the end of the resto work when I can charge & run the system. I'm gambling that all the other parts replaced will be good (they are all non-moving parts & the compressor is the most expensive) If a new compressor (or rebuild) is bad it will usually show immediately - noise, lock-up, incorrect pressures.

A mock up with the old compressor is a great idea. I'll do just that with the block off the frame. The downside of this project is I removed the system forward the "manifold" in 1993, and of course wasn't keeping a good record. But that's what I bought my 72 for (kidding, but it helped), so I have a respectable reference.
Only area I'm a bit stumped is some of the retainers forward the manifold. I had a bunch of retainers with the Compressor etc, all the years figuring it was all A/C..... Looking at my 72 and from other info......Most of it was for other components, some ID'd, some not. Here are the retainers if interested
