Unser Rear Suspension
62-67 Chevy Nova
1.
Remove Rear Suspension: Raise the car and support it with jack stands or a lift. Remove the exhaust,
drive shaft, rear end, and all rear suspension components including the rubber bump stops. Disconnect
fuel lines and remove fuel tank. Remove fuel lines, brake lines, and E-brake cables from bottom of car.
These can be re-routed through the holes in the chassis brace after installation.
2.
Prep for Welding by raising the chassis brace into its approximate position and mark all areas that will
be welded. These areas should be ground down to bare metal to provide the proper conditions for
welding. (Any carpet or padding installed on back side of weld areas should be removed at this time.) To
position the chassis brace, the rear flanges of the chassis brace should be clamped tight against the leaf
spring boxes while the chassis brace is pushed up against the bottom of the car and centered left to right.
5/16-18 X 3/4" BOLTS
(THREAD INTO FACTORY SHOCK BOLT HOLES)
CLAMP THESE FLANGES TIGHT
AGAINST THE FRONTLEAF SPRING BOXES
TO LOCATE THE CROSSMEMBER.
SLIP OVER FACTORY FLOOR SUPPORTS
FRONT SUPPORT TUBES SHOULD FIT TIGHT
AGAINST CROSSMEMBER FOR WELDING
FIT BETWEEN ROCKERS
FIT BETWEEN FRAME RAILS
3.
Repeat step two with the rear cross member and front supports. Depending on the car, minor
trimming/fitting may be required. Bolt the upper rear crossmember to the car using the four supplied
5/16”-18 x 3/4” bolts. These bolts will go into the factory shock bolt holes. This will locate the
crossmember in the proper location.
