I heard from someone else that it was a larger condenser that was needed -- not an evaporator. I can tell that there is more room up front for a thicker condenser. I am planning on keeping my car running on real R-12 since I bought a bottle before it became too expensive. But eventually for everyone it is going to boil down to either finding a blend that works well or convert to R-134a (or do without). If it were chemically possible to find a better substitute, I'm sure it would have happened by now. There is enough money at stake to motivate these chemical engineers. When I swap out frames next year, I plan on replacing all the hoses with ones that are R-134a compatible. Since the system will be all apart, I would like to know if I can go on and convert to the R-134a compatible oil and still use R-12. Can anyone say? Also, is there an advantage to using an automatic adjusting orifice tube with R-12, or would it work at all? Walt
