Does anyone have a source or part number for an AC compressor for these 4d55/4d56 blocks?


The Mitsubishi's used a small square compressor that mounted under the injection pump. The Dodges used a Sanden pump that was over the power steering pump. You may want to try to contact Mike Warme, I know he has several brackets and pumps. It will cost you a $300 to get the pumps rebuilt but it is well worth it.
