I started with Vans 60Amp alt. kit and the mounting h/w. This involved some modifications to the hardware as documented in Van's instructions. The most eyeball intensive procedure was to jogel the aluminum tension arm for the alternator so that the belt from the engine ring gear will align with the alternator pulley. It all fits and aligns well.
However, I have seen several post that complain of cracked tension arms...my solution was to buy an extra aluminum tension arm from Van, and I need to go shopping at my favorite auto parts store for a similar geometry part that is stamped out of steel. I still have not done this, but it is on my to-do list...
