Parts Included:

1 - Cap 2 - 10-32 x 1.25” Hex Screws

Note: If you need to adapt your spark plug wire boots and terminals to ﬁt the towers of the PN 8433

Cap, MSD offers a kit of nine boots and terminals, PN 8849.

The PN 8433 Cap ﬁts all of the MSD Distributors that use the GM Socket style cap (MSD PN 8437). It will also ﬁt GM Distributors that use a “window” style cap.

Before installing the new cap, note the location of the spark plug wires. It is a good idea to mark the location of one wire before removing it while leaving the other wires connected to the old cap. Then, with the new cap installed, you can install each wire individually avoiding any confusion.

1 - Wire Retainer 2 - 1.5” Phillips Head Screws

After installing the spark plug wires, position the retainer over the boots. Align the mounting bosses and use the supplied 1.5” self-tapping Phillips head screws to hold the retainer in place. It may be necessary to apply a slight amount of lubricant to the boots to help them seat into the retainer properly.
