I haven't done my truck yet, but I converted my car over to R-134A about 2 years ago. I took the whole system apart and drained as much of the old oil as I could, and used the conversion kit you can buy at WalMart or Autozone. After two years, it's still keeping cold on our 104 degree July days. Just put in the same number of ounces of R-134A as your R-12 sticker calls for - it's a 1:1 crossover. I also recommend the oil they call maxicool. It's a molybdenum blend, and it seems to quiet the compressor down some.
