5.
Prep Rear End: If re-using a rear
end, tear down the rear end to just a
bare housing. Remove any spring perches
or brackets. For the saddles and panhard bar
bracket to be positioned properly, it is critical
that they fit tightly against the bare axle tubes. Any
extra material on the tubes will need to be ground away
to provide a proper fit. Prep for welding by removing all paint,
oil, and grease where new brackets will be installed.
6.
Assemble Truck Arms and Rear End Housing: Install
truck arms onto the front crossmember using the
supplied 3/4"-16 X 5-1/2” cam bolts and spacers.
NOTE:
Install the cam bolts in the center of adjustment
as shown. The flat side of the bolt should be facing
upwards. Install rear end housing using the
supplied U-bolts and nuts as shown above.
Do not fully tighten U-bolts at this time.
7.
Adjust Rear End: Raise the rear end to the desired ride height, relative to the car. (Suggested ride
height is about 12 ½” center to center for the shock bolt
holes). Support the rear end at this height and center it
in the car. The center to center distance on the top side
between the two truck arms should be 39” as shown.
The distance from the outer flange of the rear end
housing to the truck arm should be the exact same on
both sides. Once the rear end is centered, and at ride height,
spin the rear end housing to achieve the desired pinion angle.
Now, double check that the rear end is in the proper location and
tighten down the U-bolt nuts.
