I have a 91 Silverado w/a 5.7. The compressor is leaking out of the front. While I have it apart I would like to retrofit it over to 134a. The list of items I am going to replace include. The compressor, dryer, orifice tube, condenser, o-ring kit and hose assembly. Can i purchase these from a 94 truck so everything is 134a ready instead of doing a retrofit kit to the r12 lines? What interchanges and what doesn't?
Thanks
Mark
