RV2 AC compressor Rebuild help

This thread has been very informative. I have a 1964 Chrysler that I need to rebuild a compressor for. I picked up a core from a yard here in Northern California and unfortunately instead of giving me an RV2, which I specified, they gave me a V2.

My question to the group is can one get a crankshaft, rods and pistons and "make" a RV2 or is the bore different and/or the heads different?

Is the case (block) radiused for a longer length rod on the RV2 versus the V2?

All the guts on this spare look very good. A shame.

Please advise if anyone knows.
