A. Install the connector bracket to the front of the
stock bracket at the power steering pump with
the two longer metric fasteners provided. Some
vehicles use metric and others use standard
SAE threads. Check the threads on the fasten-
ers you have just removed against the ones
supplied prior to installation. Both metric and
standard fasteners have been provided for your
convenience. Leave the fasteners slightly loose
until all fasteners are started.
B. Position the main supercharger mounting plate
and install the fasteners as shown in the graphic.
Make sure not to forget the 1/8" long tube spacer
behind the plate on the inward bolt.
C. Remove the fastener securing the stock bracket
to the cylinder head on the outward side. Install
the cast aluminum mounting bracket behind the
new mounting plate and on top of the tab on the
stock bracket (where you just removed the
fastener). Place the 3/8-16 x 5-1/2" bolt through
the plate and into the head, passing through the
tab on the stock bracket.
D. Remove the smaller alternator fastener and
install the upper stiffener plate as shown. Do not
secure the stiffener until the supercharger is
installed.
E. Attach the stiffener rod between the cylinder
head and mounting plate. A one inch spacer is
used at the cylinder head as shown in Fig. 6A-a.
F. Secure all other bracket fasteners at this time.
