Wanted: part numbers for 1991 AC switches

[VetteMed]

If anyone with a 1991 could go take a look at the part numbers on the 3 AC switches, it would be a huge help. I'm trying to troubleshoot my AC system after charging it, and I am wondering if I screwed up which switches I used (I had some spare lines from a different year and can't remember if the switches I used were the originals or the "new" ones which may be incorrect).

Thanks!

Are you talking about the hardline pressure switches? My 91 has two of them.

There's 2 switches on the high pressure line (narrow diameter) and one switch on the discharge side of the evaporator. I'm trying to troubleshoot my AC system and want to rule out the possibility that I mixed up the correct switches with ones out of my parts pile.

Probably not needed at this point - looks like I might have found the problem in my system.
