G-Comp Rear Suspension
62-67 Nova
10.
Check Alignment and Clearances: It is recommended at this point to cycle the suspension though
its travel and check for any clearance issues. This is also a good time to double check that the rear end
is aligned properly with the car and the pinion angle is correct. (use the cam bolts on the truck arms to
adjust the alignment)
11.
Finish Weld: Remove the rear end, panhard bar, and truck arms from the car. Fully weld the cross
member, chassis brace, and front supports to the car. Weld the saddle brackets and panhard bar bracket
to the rear end. NOTE: It is a very good idea to only weld a small bead at a time, then move to a new area
and allow the first area to cool completely before welding further in that area. This will greatly reduce the
risk of warping, especially on the rear end housing.
12.
Re-Assemble: Once all of the welding is complete, everything can now be re-assembled.
Secure the truck arms to the chassis brace using the cam bolts and cam spacers as shown in step 6.
Now is a good time to fully assemble the rear end by installing gears, axles and brakes. (This can also
be done after installing the housing into the car)
Raise the complete rear end into position. Attach the rear end to the truck arms using the supplied
U-bolts, washers and nuts.
Install the panhard bar using the 5/8”-18 x 6” bolt and lock nut on the crossmember end and the 5/8”-18
x 3 ½” bolt and lock nut on the housing end.
Install your coil over shocks using the supplied 1/2”-20 bolts. The 2-3/4” bolts and 3/16” wide spacers are
for the bottom while the longer 3” bolts and 5/16” spacers are for the top.
Note:
This kit is designed to use
shocks with a compressed length of 10” and an extended length of 14”. Shock ends should be ½” bearings
with a mounting width of 1”. For recommended part numbers please visit our website or contact one of our
tech experts.
Re-install the drive shaft, fuel tank, fuel lines, brake lines, and E-brake cable etc…
Bleed the brakes.
Fill the rear end with fluid.
