MustangPaul said:I would have never converted from R-12 to 134a. 134 just doesn't cool as well.
As for the backseat of a fastback, the backseat of my coupe was almost useless, so I can't imagine the backseat of a f'back.

I did the R-12 to 134a conversion in my F-150. The R-12 was all gone out of it and the AC wasn't cold anymore of course. So I filled it with stop leak and 134a. Mine seems to do a pretty good job of cooling it down really fast.
