Selling an E30 M20 alternator pulley made from 6061 billet aluminum. This replaces the OEM hardware which is made up of 2 thick steel washers and 2 sandwiched steel plates. Overall about ~40% lighter than the OEM setup, with the same rotating diameter. This doesn't underdrive or overdrive the alternator, as it isn't recommended to do so for a street car with all accessories.
You re-use the big thrust washer sitting on the metal fan side, as well as the M16 wavy washer and M16 nut on the front side (hardware not included, reuse what you have).
