DISCLAIMER, I SELL AND
SERVICE MANY OF THESE SYSTEMS
The plates you are selling from the 80's probably used R12 refrigerant and mineral
oil. This is NOT comaptable with 134A and PAG
oil. They will need to be scrubbed metioucsly of any oil from the old system before reinstalled in a new instalation.
Another problem may be the swagelock fittings. Are they all in GREAT shape, no distortions, nicks, etc from
removal from
icebox? This will make a new leakproof instalationa a chore.
If there is not enough copper to remake the swagelock ends, they may need to be sent back to Seafrost for a new set of copper coils. This is about $150 a coil.
Used holding plates can be a great deal if it fits your bill. Or scrap it out for the scrap copper since there is a fair amount of copper in these two plates.
Just some honest
advice from observations in the field.
