ac question

Several companies make compressor brackets for Mopar small blocks. All use a Sanden as in post #2, as do most all hot rodders. Sandens come in 3 lengths I know of: 12, 13, or 15 cc, and either 5 or 7 pistons. The SD7H15 seems most common (7 piston), but many use a "shorty" 12 or 13 for space. You can find "York to Sanden" adapter brackets on ebay. If cheap, you might be able to adapt one to your factory brackets (never seen that). You can find newer compressors (Sanyo?) on 80-90's small blocks (pre-Magnum) on trucks and vans. One of those could fit.
