The 1996 impala ss alt. is the application it is rated at 140 amps. You will need to get a different terminal lug for the wire that runs from the back of the alt. to the battery and also may need to use a different serp. drive belt as the pulley may be a different size.

I swapped my pulley from the stock 120a unit on to the 140a unit. I also had to reclock the alt case to match the stock so that the regulator plug is accessible. Real easy upgrade and works great. I did not have to change the belt.
