Well the way I built it is kind of like being turned on a lathe. I built it like this: First I tack welded 4 tangs onto the center section of the pulley, then drilled and tapped a whole in each one. Then I slid the outer section into the tangs and secured the two together with bolts through the holes that I tapped. Then I used a feeler gauge between the crank pulley to true it up and down. Then I put the belt on loosely, just enough to turn the pulley and pushed a sharpie into the pulley with the engine idling to find the high/low spots and adjusted it until it was true that way. Then I tacked the two pulley halves together, removed the tangs and had a co- worker run water over the pulley as I welded it so that it would not warp. It is currently installed and is very true. I just don't see it coming apart. but having a correct pulley would help me sleep a little better at night. Thanks for the degree on the windshield, I had no Idea, I will measure tomorrow, how far from the dash is it supposed to be? Right now I have 8 1/2" from dash to windshield and 4 1/2 from windshield to hood.
