Install instructions should be the same as the Pertronix ignitor1,

The transmission bell housing contains the torque converter, the fluid based clutch that every automatic transmission has. There is a removable inspection cover bolted to the bottom of the transmission with 4 bolts. The engine flex plate is bolted to the crankshaft flange in the middle, and the torque converter bolts to the flex plate with 3 bolts. If those bolts are loose, or the flex plate is cracked, the engine will make a knocking noise that is non rhythmical, and comes and goes. It is worse when the engine is cold or running rough. It can sound like it is coming deep within the engine, but it isn't.
