Since it's almost spring and my engine is about to be all back together...it's time to turn to my A/C system and get it running well again. It's currently the original setup but missing a few things when I compare my car to the original drawings of the '69. It's missing the Dehydrator and the Muffler (bolted right up next to the compressor).
Being all original minus those parts means that it is still R12 which is very expensive.
1)Should I change over to R134? 2)If I switch over would this be a noticable change that would look much different from the R12 system? 3)My mechanic who would do the work says that to make the switch he'll just put different nipples on so that the R134 hoses will connect to the system...is it really this simple? 4)Can I leave off the muffler and the dehydrator or should I find them and put them on?...I haven't seen a muffler anywhere, but I'd like to get one just so that it looks original.
