Seems like a shit tonne of work... i unbolted it from down below, and rebolted it in up top, only fab/modification i had was to drill 2 3/8ths holes in a peice of metal about 1.25" apart, and clearance that bannnanna bracket. a couple new bolts, and a 1/2" washer stack... done.
K.I.S.S.
Grinding alternator case's for clearance is stupid.... have fun when you blow an alternator on the trail, or even the street. I can replace an alternator in 15 minutes, without having to grind anything. And thats a CS-144...
