I did the upgrade this evening and it is beautiful.The gauge now pretty much stays right in the middle regardless of what is running.the whole thing only costed like $60.00...,25 bucks for the taurus alternator from the graveyard and $35.00 for wire,ring connectors, the fuse and holder, plus I got an extra fuse to keep in the glove box.I did have to grind the bracket a bit and clock the alt.I think with some of the other model ford alternators will just fit right in with no grinding, The pulley I used was from the existing alt and it looks like it may be an overdrive one,cause it is smaller than stock.
