95 Riviera SC, AC compressor question.

I just bought a 95 riviera supercharged and the ac compressor is locked up tight. The car is about an hour and a half away so i cant pull the compressor to compare to another. Does anyone know if there's a more common car out there that i could use a compressor from. Im not concerned with it working, I just need one that bolts up the same and the belt can ride on. From local junkyards, I can get one for a 95 bonneville or a 94 regal. I just dont know if either fit. Any help is appreciated.

Some of your options are shown below, they all use the same HD6 compressor.

Buick LeSabre Custom 1995
Buick LeSabre Limited 1995
Buick Park Avenue Ultra 1995
Buick Regal Custom (1994 - 1995)
Buick Regal Gran Sport (1994 - 1995)
Buick Regal limited (1994 - 1995)
Buick Riviera 1995
Oldsmobile 88 Royale LSS & 1995
Oldsmobile 98 Regency Elite 1995
Pontiac Bonneville SSE 1995

Thanks but i found a bypass pulley that fit.
