MSD 8491 Tach Drive Adapter

Regular price $27.98

The standard tach drive for MSD tach drive distributors is a 3/16 In. tang drive cable. In most cases this type of drive will work, but for those who require the 0.104 In. square drive (Corvette style), MSD offers a tang to square drive adapter to fit all MSD tach drive distributor assemblies.
