Here's the solution for racers without
space for a standard distributor

Does your vehicle have clearance issues due to the firewall or intake combinations? Front Drive Distributors are belt-driven from a pulley installed on the camshaft. The 9mm belt is wider than any other, and this is the only front drive distributor with adjustable belt tension. The band clamp mount allows for easy rotor phasing adjustment. These distributors work great with MSD's Pro Cap, and they come complete with mounting bolts, cam pulley, and drive belt. And don't forget to plug the block's distributor hole using an MSD Pro-Billet Oil Plug with (121-8513) or without (121-8512) oil pump drive.
