Well I'd like to know if there is a way to check to see if a compressor is good before installing it ?

I have 2 compressors I can use but they are not identical.

One says General Motors Corp. one... Well one is a Delphi brand and the other is a Harrison brand. One says r134 on it, the other one says r12 on it.

So I have no idead wich one to pick and I dont know if they are good or not.

Amazing! I was just talking to the HitMan today and was asking him the very same question. I have 3 used compressors and was wondering which one to install on the Squash.
How do we tell if a compressor is good, providing of course it is not seized?
Before yall say it, I know a reman is $107 bucks of so, but heck, $100 bucks is a $100 bucks......

I believe the Harrison is the OE compressor.

Because the Harrison you have is made for R12, what the car came with.

So how do I test them and which one is the best on to use ?

My cousin told me to connect it to a 12v battery and see if I can hear the clutch engaging.. waddoyou guyz think ?

That's fine for testing the clutch but it won't tell you how well/if it will move the refrigerant. (I don't know how to test that.)

Sadly about the only way to tell the condition of these things is to put them in service on the vehicle....unless someone has a compressor test rig set up....which I have thought of making one day....with recoverable refrigerants of course...probably have to have one for R-12 and another for R-134A and get them EPA certified.....To avoid going to prison and paying a $20,000.00 fine for endangering mother earth....
