Installation Option: This
Cap can also be bolted
down to an MSD Pro-
Billet or Billet Distributor
base with the supplied
hardware. To accomplish
this, the spring clips must
be cut off (Figure 12).
Note: When the cap is
bolted down, the location
of the spark plug wires
must be changed.

VACUUM ADVANCE LOCKOUT
If you do not want to use the vacuum advance
canister of the MSD Distributor, MSD has supplied
the distributor with a lockout mechanism. The
Lockout bolts in the position of the vacuum
canister and will hold the pickup assembly
firmly in place. The installation is easiest with the
distributor out of the engine.
1. Remove the two Allen head screws that hold
the advance canister (Figure 13).
2. Remove the snap ring that holds the magnetic
pickup assembly in place. This is easy to do
with a set of snap ring pliers by straddling one
of the reluctor paddles.
3. Gently lift up on the mag pickup plate and
slide the vacuum canister out.
4. Install the Lockout Plate in place of the
canister. Install the two retaining screws.
5. Install the supplied screw and washer through
the Lockout and tighten.
6. It is important to make sure the pickup plate
is parallel with the housing of the distributor
(Figure 14). If it is cocked or slanted, the
paddles of the reluctor may contact the
pickup. Check the clearance by rotating
the distributor shaft. If necessary, use the
supplied shims under the Lockout hold-down
to correctly position the pickup plate.

Figure 13 Removing the Vacuum Canister.
Note: If no shims were required, use one beneath the washer of the Lock-Out Hold Down Screw.
7. After checking the reluctor to pickup clearance, tighten the Lockout retaining screws and install
the snap ring.
8. Install the distributor, rotor and cap. Check the timing when complete.
Note: Do not forget to plug the original vacuum advance hose.
