TTI spool mounts vs AC compressor

There's no way that would work. The two measurements you see are 6" from the spool bolt to the outer edge of the power steering pulley, and 8.5" for the AC compressor body, assuming you cut the tab off. The TTI spool mount is on the front side of the old rear AC mount hole in the block.

I went to double check just now. You got my hopes up for a moment!
