anyone know of an a/c convertion kit for my 93 d250? I would like to update it from R12 to R134A.

 

There probably isn't a kit. Just replace your o-rings, drier/accumulator, flush out the system, and refill with 134A. There are adapters to screw onto the R12 lines so the R134A gauges will hook up. I'd replace the orifice tube too...you can either go back with a stock type or there is usually a higher dollar auto adjusting one that is supposed to be better.

The guy at auto zone told me all i need (1992 d150) is to flush the R12 out and thenput a can of this stuff that switches it to R134a from R-12 then fill it with R134a the rest of the way. My uncle did it on his chevy and that is all he did.

 

I may call my contact at Dodge on this.
