What is the big pulley on the other side of the engine...power steering?
Ya, its power steering. I'm using the original rack from the mustang. I calculated the rack length I needed when I built the suspension arms. The rack was within 1/2" of what was needed. So, I'm using that rack. Its easier to run power steering, than to get a new rack or de-power the one I have. I also need a pulley at that point on the engine anyways.

Flat belt alignment is critical. Besides fore/aft pulley alignment, the shafts must be parallel in the vertical and horizontal planes. If they are not, the belt is tighter on one side than the other. The wider the belt, the more critical the loading is (this should be a K6). The belt fails by shredding on one side as it comes apart. It is no fun to buy a $15-20 belt every month.
This is why I was trying to steer away from moving the alternator. I've built many go-karts, when I was younger, 3 of which ran off belts, like a lawn tractor (Had clutch to engage belt) . I went through so many belts, I'd have a spare of whatever size I used, and the guy at TSC recognized me whenever I bought a new one. This was before I owned a welder, and could make something strong enough, that it wouldn't flex.
I think I may make a new bracket for the alternator. That seems to be the majority vote. I think I'll be able to make it work. I did a lot of measuring tonight. I've got some numbers, and I'll see if I can come up with a design that will work. I'll try to make it adjustable, so I can move it fore/aft.
As I've mentioned before, I'm really getting tight on my budget for this car. I want my only expense on this alternator relocation to be in a new belt. So, I wont be getting a new alternator. It is tempting to just take off the alternator all together and be done with it. If I did that, and left the battery on a trickle whenever it was home, it would be fine. But, I'd hate to be stranded without being able to start the car, or without power for headlights at night.
We'll see what happens tomorrow...
