Wtb ac compressor

[xjjk]

My ac compressor won't hold pressure- leaking behind the clutch so it's the shaft seal that's going I guess. Anyone have a known good compressor they'll let go cheap? Are there changes in these thru model years? This is a round body old style york w/ service valves, might work for someone to hook up oba? Pumps ok loses pressure over 48 hrs.
