1978 El Camino, bought used , 350 engine. I have replaced the alternator recently and just yesterday replaced the waterpump. For some reason the alternator pulley does not line up with the fan pulley. It actually sits a little sideways, which causes the belt to rub on the pulleys. I have tried to use washers to adjust the alternator either way, but can't get it just right. I am wondering if I need to replace the upper and lower alt. brackets. Maybe someone installed the wrong ones??? Just wondering is anyone else had this same problem.
