Need some help identifying what A/C pumps I have.

[Wizard]

I have 3 A/C pumps with these part numbers. Can someone decode them or can someone tell me what the difference in A/C pumps are? Big pumps. Little pumps? What is correct way to identify which pumps go to A,B, or C body?

The part numbers on them listed right under the S/N# are.

P/N# 2843602

P/N# 2865391 V

P/N# 295119

Thnks,

Wizard

I was at the Chrysler as Carlisle show at my spots and someone told me one of them is for A-body and the other one with the cast heavy duty bracket is for a early 60's car. Not sure what the big one goes to but probably a C-body. I love R-12 and wish I could find someone to put in R-12. Going to get these rebuilt and completly done over.
