AC compressor brackets

The Chrysler C-181 compressor is similar to a Sanden internally, and a good choice if it fits your intake manifold. Downsides are it has rather funky plumbing connections and is less available than a Sanden. Many companies make Sanden brackets for a small-block. If a normal Sanden body (H14 or H15) will hit your intake, a shortie (SD7H13 for Civics, etc) may fit (1" shorter), though might need spacers to fit the rear ears to the brackets. You can also get various rear heads for $20 on ebay to relocate the plumbing. Google Images hot rods for many ideas.
