Hi, I have what I think is a pre 1958 A/C compressor. It is flanged on the back so I think it can be rebuilt. What I would really like to know is , do you call this compressor an A5 like you do for a 1958 thru 1961 sealed compressor or does it have a different designation. Any body wants it can have it for $30.00 plus shipping. Don't know if it pumps but the clutch works. Ed:confused::confused::confused:
