Need some advise on my 1965 Barracuda with a 318in it. I have had the worst time with alternators. The one that came on the car was an oreilly's Ultima unit and it died and wouldn't charge. Got another one and it overcharged and blew up my optima battery (was hissing and spewed all over my drivers side of my engine bay destroying a bunch of stuff). I had a 1 wire tuff stuff from summit in my garage so i threw that on, and the very next day the altenator was making a loud whine. I checked the alignment with all of these alternators and the pulleys do not line up. I bought a brand new alternator bracket for a 67-69 small block to make sure I had the right one as the original seemed a little bent or was a 70+ unit. I'm wondering if the crank pulley or water pump pulley is wrong. In pictures I see online they should all be single groove for a non AC and non power steering car.
