Default AC Compressor help

I just completed replacing my VIR valve and flushed my AC system. I am looking at R4 compressors and I'm looking at one remanufactured and one brand new. The problem is the new compressor shows a different style clutch/pulley from my old R4 compressor. Would the new clutch/pulley work on my V-belt system? or do I need to swap the clutches? The first picture is what I have currently and the 2nd picture is what im wanting to buy. If anyone has installed the new clutch/pulley could help me out that would be great.


This is my old compressor.

This is what I want to buy.

I just rebuilt the AC in my 77 and replaced the compressor with what looks exactly like the one you’re looking at. After reassembly the belt runs in it just fine. I haven’t run it all that much, but on a short cruise the belt stayed in and didn’t squeal. She’s back in the garage for a coolant leak (new) under the car at the heater core. If it’s not one thing with these cars, it’s another!

I just replaced my compressor with the new one from Zip. Installation bolts were a different size than original. Shop got it in with new bolts and seems to be working fine. It is an A-4 compressor. On to creating ductwork!
