The newer A/C clutch definitely works on the older compressors. I had a broken older brush type clutch on my 60 Imperial, which has the V2 compressor. I replaced it with a newer clutch for the RV2. Works great. Yes the diameter is slightly smaller on the new clutch but I still had enough adjustment range to tighten the belts. The 60 parts book shows two clutches, one is 7 ½ diameter the other 5 1/8”. By the way, the brush assembly for the older style clutch is the same part as a 63-72 Ford t-bird. Part price $35.00 at Thunderbird Headquarters.

I believe George McKovich changed clutches on his 57 300C. As far as bearing on early clutch, I have changed them out. Not hard to do. The early brush style is the down fall of that clutch. Putting a light coat of silicon grease on the commentator will help longevity of brushes.

Same bolts on front of V2 or an adapter / mount plate changed ? I have an AC equipped D , compressors look the same up into 70’s , but huge clutch on early ones . Anyone know for sure? Or maybe a whole ~ 1970 V2 with clutch and pulley fits same mounting ? Rebuilt later ones available . What is wrong with the old one ? In my experience bearing it rides on when free wheeling seizes up or balls fail: grind up . Other wearing part might be a brush ? I think later one magnet coil is stationary ,?, no brush . But not sure any of this . Someone must know. Related .. you really need a new receiver / dryer if changing compressor ? Good to know about this from AC guy.. and 134 change over .
