well, ran into another clearance issue between the S/C pulley and a bolt for the A/C bracket... solved it by recessing the bolt. Now I have more than enough room.

All hardware that I'm using for the mount is metric, so obviously I cant get Grade 8, so therefore I'm using all 12.9 grade. For comparison, Grade 8 is 150,000 psi tensile strength and 12.9 is 176,000psi. Additionally, Ill be using blue threadlocker since lock washers are useless with grade 12.9 bolts.

This weekend, I have to make 2 more spacers. I have a foot long piece of 7075 Aluminum round bar stock. I gotta cut 2 sections, both under 2" long, and then drill them down through the center. Should be fun, especially when I'm making them fit to 1/10,000th of an inch tolerance.
