Sounds good, I finally got the right connector so I will solder that up when I have some free time.

The belt looks like it will work. Count on using some 0.030", 0.020", or so shim stock to get the pulleys in the correct line. It takes more effort to shim it, but it is easier than getting the bracket dead on. You can also use a standoff too long and grind it down to be perfect. You may want to investigate lowering the idler a tiny bit to get more wrap on the AC pulley. AC belts have a tendency to squeal, especially when exposed to dust.
