i am running a 3g alternator which is right much larger than the stock alternator, but i mounted mine just below the blower, i drilled a new bolt hole in the plate that the blower sits in. i only got one bolt in and had to space the pulley on the alternator with one washer, but everything lines up good, and i haven't thrown a belt since i rigged it about 500 miles ago. i looked for a picture, but the alternator is so far hidden you can't see it in any of the pictures.
