Who's done AC on an LS engine

There's a company that makes adaptor fittings from the compressor used, to generic A/C O-ring fittings. You then get some generic fittings and swage them into your old A/C lines. Worked great on the (non RX-7) A/C equipped engine swaps I have done.

Swagelok makes stainless metric compression fittings that I've used to splice OEM hardlines to other manufacturer OEM compressor discharge lines. 2 years later still no leaks. It was as easy as cutting both lines in half at the correct lengths and tightening two tube nuts.
