I finally had my Indy check the AC on the 300D 2.5t. It still has the old R-12 system. He will black light the dye to check for leaks as it is low in sight glass. He suggested finding some R-12 as cheaper and better long term than doing a 134a conversion unless there are major leaks. I can't do any AC work myself. He also mentioned that Freeze 12 was compatible with R-12 but may do long term damage. In truth I have only skimmed the many posts here on AC but now I need some info.
