?'s about getting A/C Working on 75 Duster

Now that my wife and I have a kiddo...the A/C is important :)

I'm trying to get the A/C working on my wife's car which is a 75 Duster 360

I was told by her FIL, that before the engine was pulled for an overhaul, the A/C worked (when she was 16, she's now 32). I recently had the lines redone (using new barrier line), I got a new drier and new Expansion Valve, and got the electronics on the inside working (needed a blower motor switch).

What do I do about the compressor? I jumped the pressure switch and it turned over and sounded like an air pump should (I only did this for a second to verify that the clutch worked and compressor didnt have a nasty knock), but I was warned by my FIL, that the RV2 compressor is known to leak.

I plan on going back with R12 (for efficiency) and want to make the A/C nice and ice cold again in the cabin :).

What do ya'll think I should do with the Compressor? about every other component in the system is either refurb'd or new, but a compressor is a big chunk of change...
