Before You Start
Switch Suspension 60-66 C-10 cowl mounted hood hinges are the perfect solution for tire clearance or cleaning up the engine compartment. Installation requires drilling, cutting, and welding and can be completed in 4-6 hours. If you or your installer aren’t experienced with this type of work, please seek professional help. Read these instructions completely before starting.
Install Steps
- Remove the factory parts. Remove your factory hood, hood hinges, and wiper cowl.
- Mark the centerline. Place a piece of masking tape roughly in the center of your cowl and draw a vertical center line. There will be a mounting hole for the cowl panel very close to center.
- Mark the hinge locations. Measure out 22 13/16″ from the center line (left and right) and draw a vertical line on the tape for the hinge bases. Double-check your measurements — the distance between the two outer marks should measure 45 5/8″ (center of hinge to center of hinge).
- Trace the hinge base. Disassemble the hinge arms from the hinge bases. Set each base on top of the cowl, positioned 1/2″ back from the face of the cowl and centered on your line, then trace around it.
- Cut the sheet metal. Cut along your trace lines with a cutoff wheel or body saw so the hinge base can drop down inside the cowl, then check for fitment. If you run windshield wipers, cut carefully around the wiper mounts.
- Make a hinge face template. Trace the face of the hinge base onto a piece of paper or poster board and mark the 4 mounting holes plus the slot for the hinge arm. Line up the template’s center with your vertical line and mark the hole and slot locations.
- Drill the mounting holes. Drill all 4 hinge base mounting holes with a 5/16″ drill bit, and the top and bottom of the hinge arm slot with a 9/16″ drill bit. Finish cutting the slot with a body saw or cutoff wheel.
- Bolt up and mark final holes. Set the hinge base in the cowl with only two bolts — it should sit flat against the inside of the cowl with a slight gap on the outside. Mark, remove, and drill the final two mounting holes with a 5/16″ bit.
- Install hardware loosely. Insert the hinge base and loosely install all mounting hardware, including the hood lift strut bracket if equipped. The outer mounting hole may need 1-3 washers to make up the gap — this varies truck to truck. No washers go on the inner side; it should sit flat.
- Torque and check clearance. Torque all hardware to 25 ft-lbs. Slide the hinge arm through the cowl, reassemble with the hinge base, and run it up and down to check for clearance. Do not install the hood lift struts yet.
- Weld the hood mounting pads. The pads need to be welded to the hood brace on the underside of the hood — the weld heat won’t affect the exterior paint. Either repeat your cowl measurements (22 13/16″ from center) on the hood brace, or loosely mount the pads to the hinge arm, set the hood on the truck with the inner fenders and front wheels removed, and tack weld once centered and fitted correctly.
- Finish and install struts. Test fit, make any adjustments, then finish welding the hood mounting pads. If equipped, install the 4 hood lift struts with the lower mount to the outside of the firewall bracket to triangulate the shocks and stabilize the hood.
