Found some GREAT info on the air conditioning systems

I had to do some quick research this morning when board member Powell72 came over to pick up Fred to get the A/C charged. He needed to know what the original R12 charge amount was. In doing a few searches I ran across a couple of excellent posts on the subject.

The first link is from the chevytalk.org forums where our own gchemist is a moderator. This guy had a square body that had nothing but the evaporator and wanted to complete the system. Great write-up with a ton of info. About mid way through the first post is a link titled "A\C system capacity", which is a .PDF file from NAPA that lists the OEM refrigerant and oil capacities are for most all vehicles, and it appears to go up to 2004 or so.

The other is from thirdgen.org, and is a great detailed write up on converting from R12 to R134A.
