Factory A/C Conversion

[noreastfish]

I have a 1970 Challenger with factory A/C. It has not worked in years. I was wondering what I would need to do to get it running again. Is there some kind of conversion kit. Looking for a starting point. Any help would be appreciated. All of the original equipment is in place as it should be.

Small block or big block? 

Plenty of ways it can be done....  Stay stock..... Replace the RV-2 compressor with a Sanden & convert the system to R134.... Get crazy & replace the whole system as some have done though I don't reccomend it....

Here are a couple of ways to go.

I need to do the same work.

The first place I'd start would be to have a shop charge the system with nitrogen and add a dye kit. Then start looking for the leaks. Not often do the hard lines go, but the junctions where hard and rubber meet, the O-rings and the condenser and evaporator are the most likely. once you've found the leaks, have a shop (or buy the kit yourself) and flush the system to remove the schmutz. I'd have the compressor gone over as well. As mentioned, your original system used R12 and it's getting harder and more expensive to find it. R134 conversion kits are out there. Good luck
