Let's see those parts were like 300 for an evaporator/expansion valve, and about 100 for R12. That was for a leaking evaporator. Just one part and it adds up. You need someone to tell you what's wrong.
Wow, I'm surprised you were even able to get any R-12 refrigerant. Why did you just do an R-134a conversion since you were in there? Wouldn't that be cheaper in the long run?
