These are off of my '64 Corvette, they do work they are just slow. Sold as a pair only. Part number can be seen on pictures of the bracket, also on the body of the motor is 5045374 for the RH & 5045375 for the LH. Price is firm at $ 360.00 delivered anywhere in the United States. New Units are $ 750 a pair plus tax & shipping.

These are perfect if you do not have HL motors, as I said they do work but are slow, or they can be used as cores to have them rebuilt.
