MSD Pro-Billet OptiSpark Distributor - Optical Pickup - Electronic Advance - Socket Style - Black / Red - Pin Drive - GM LT-Series 1992-97 R040002 Wheel StudLeave it to MSD to build an all out performance distributor to replace the OEM GM LT1 Optispark! We machine an entire billet block of aluminum down into a precise housing that fits in place of the factory piece. Then, we fill it with a reliable new pick up assembly, a trick timing adjustment mechanism and top it off with an all new MSD distributor cap! The pick up is an advanced optical encoder, a different style of optical pickup than the OEM. This
