Never again will i do business with excessive amperage. i ordered 2 300 amp alternator's (which work fine), but I also bought a bracket from them and i've had nothing but problems with it. 1st off it shipped in a week after my alternator's arrived b/c there cnc machine was supposedly down (believeable). Then when it does arrive it looks beat up, like it was used in another car already, it came with no bolts or nuts, and no belt, also the pully wheel was worn out b/c they said they didnt want to buy a new one b/c they were expensive???? At this point i was pissed but i didnt return it b/c i was ready to install the damn thing and it was just a bracket so it didnt have to be the prettiest thing in the world, but today in the process of putting it on i find out it doesn't fit :/. So i have to make it fit by cutting a lot of steel. It was ridiculous, but it's finally on the car. Bottom line of this rant, Dont buy from excessive amperage!!!!!
