Year: 1973
Make: Plymouth
Model: Duster
Engine Size: Hemi 5.7
Country of Origin: United States

I'm putting a 5.7 hemi into a Plymouth duster. I have the factory AC compressor for the hemi, but it runs into my aftermarket motor mount (which is using one of the AC compressor mounting holes on the block- factory position is low drivers side). Unfortunately, it would be difficult to modify the mount, given the supporting K member is directly under the mount.

I have ~5.75" of depth space that I could fit a compressor. If I offset the compressor, I could possibly gain a couple more inches. The diameter of the unit factory was 6", and I probably have 8+" of diameter room if offset (and could possibly cut into the K frame for more). Any recommendations on compressors?
