When rebuilding the Valiant's AC I stuck with the V2 compressor and upgraded to R134. I installed a new parallel flow condenser, all new lines and also rebuild the compressor. It worked "okay" but not really stellar. Unfortunately the carbon pack shaft seal on the compressor (brand new one) gave up the ghost about 18 mos. after installation and the system has been dead ever since. I am going to a Sanden as well, but as I am going full on Magnum I'll be good to go.
The seal on the Val turned ugly. Had to remove the crank. Found a bad rod bearing........... Grrrrrr.........
Glad yours is running. Looking forward to seeing the video!
Best,
