1996 Astro Van A/C Questions

I'm replacing the A/C Compressor in a 1996 Astro 4.3L. What other Chevy vehicle can I salvage a compressor pump from that will bolt straight up?

pulley diameter is different- from a s-10 96-2002, c/k trucks, G-vans- they all use HT-6 compressors- you can swap pulleys if you have the tools...
