I have a 85 300cd turbo, the ac compressor was removed years ago. I have been looking for a replacement and have seen "GM radial R4" in several threads and in the buy parts link above. Is that the correct part number for GM ? My brother works for a GM dealer and could pick it up at a nice discount. Also, does anyone know what bracket or mount I need to install it ? As I said before, all that has been removed. Thanks, Jon

The correct Delco number should be 15-20230...I would think a good price should be $175-200
