The solenoid above the compressor keeps dying after a short time. I have had
them rebuilt & even got a NOS one on ebay...same lifespan.
the longest one has lasted is less than 4 hours.
Any thoughts?

Could be the compressor clutch is drawing too much current.

Check Voltage & Current draw at the solenoid, with the engine at a fast idle. Compare to voltage across battery terminals. You will probably find a several volt drop, thus drawing more current & burning out the solenoids. I have had several Mopars & a Ford with the same issue. Answer is to feed the solenoid with a relay drawing current directly from battery positive terminal. Relay is switched by the old solenoid lead. 12 volt headlight relays work fine. Advise if there are other issues.

I tested the current draw @ .6 a. with a DC current clamp. There is no voltage drop. I did , however, use a jumper wire to the battery to adjust the clutch per the service manual first & I gotta tell ya...it was waaay out of spec! I played with it awhile & finally got the .018 feeler just right. I replaced the inline 10 a. fuse w/ a 3 a. It appears to be working properly now. It's already over 100* this morning, so I'll have to road test early tomorrow morning. I'll post my results.
