M20 swapped 318s and Air Conditioning

[varg]

I've searched quite a bit for an answer to this and haven't found anything. When swapping from an M42 to an M20, does the AC compressor and line setup have to be altered or will the stock 318 compressor bolt up to the M20 mount? I did find a diagram of the setup on the M20 but nothing on the M42.

Dunno, but by this time the compressor, soft lines, and all o-rings probably need to be replaced just based on age. So it really doesn't matter as you'd get M20B25 parts as replacements.
