I don't know much about a/c but am keen to learn. If anyone is able to help me figure out how to make this work I'd really appreciate it!

I re-habbed a stock system a few years ago. I put a stock system in a truck that wasn't shipped from the general with AC. I did convert it to R134a. You can skip a lot of the stuff I did but some of the general procedures will come in handy. Like what to flush the re-used components with. How to switch from one oil to another in the compressor. How to evacuate the system. I hope it helps.
