Belt Tensioner

This is just the parts from the original alternator tensioner adapted to the new setup. Notice the OEM threaded slide, and bolt. As the bolt is tightened, the alternator rotates up and down tensioning the belt. This gives you about 1-1.5" of belt adjustment. You can also see on the front of the 90deg RED adapter where I cut it from the black sheet metal bracket.

The smaller recessed end (Top part in pic) gets a 10mm hex size nut to attach it to the sheet metal bracket. I used some nuts (spacers or standoffs will work too) to bring the bottom of the tension in line with the top.

I really didn't think it would be this easy, but it was. All it took was a lot of thinking and planning to come up with this method, now I pass it on. Best part is, that you don't actually have to make a single new part to mount the alternator. You just modify existing ones.
