    A while back I did a complete retrofit to a sanden compressor and to r-134a.
    here is my problem now---
    the r-134 runs at a higher pressure and the old r-12 pressure switch kicks it off when it is pressured correctly...hense I have been running with a less than optimal charge and therefore reduced cooling....

    the current pressure switch is shown below and reads 4260058 / 5950 / 3.2:4

    Anyone know of a higher pressure replacement? will the 355 or 360 switches fit? will a generic fit?

    A good Delco dealer will have an illustrated catalog, you will be able to find a generic in there. Porsche 944 which have been retro have worked OK, try that reference.
