Size of original pulley on York A/C Clutch

[Ron. Strasser]

The clutch on my Avanti's York A/C Compressor has a short and is in need of replacing. I am not sure that the clutch that is on the car is the correct size as the compressor was replaced about 20 years ago. The original compressor throw a rod while driving on the Taconic Parkway. The compressor that was installed at that time was out of a 64 Lark type that had a after market A/C unit. Until a few weeks ago the system worked fine.

The outside diameter of the pulley that is on the compressor is 6 3/4 inches. I also need a source for a replacement clutch.
