New A/C compressor

[HemiPar]

Hey all. Took the wife out for a drive yesterday. It was almost 100 here in KY. She asked if I had A/C in the car yet. I told her that it was the next big thing for the car. I have a 71 Swinger, factory A/C that does not work, 225 with a Offy 4bl and unknown headers. Anyone know where I can get a new compressor or where I can get the one I have rebuilt for R134? Thanks
