All parts fit my new LS3 engine, but don't buy this drive for use on any street rod using a mustang II style suspension with rack and pinion steering. The alternator sits about an inch from the steering shaft on the rack and won't work.

The corvette style serpentine drive places the alternator too far from the engine centerline to work with cars '40 and older - the engine compartment is just too narrow.
