Wheel Pant Mounting Instructions
For QCU Wheel Pants and Mike Harrison's Landing Gear.
By: Anthony McGee

This modification may also work with QCU gear. The mount requires a small amount of welding. You will need two 5/8-18 fine thread nuts, about 14 inches of 1/8 inch flat bar 3/4 inch wide, 4-1/4 inches of 5/8 fine threaded rod (A piece of 9/16steel rod would work but would need to fit inside the nut.), 6 AN4-10 bolts (I do not have the exact length of those bolts, you may have to use slightly different lengths), 6 large area flat washers (AN970-4), 4 lock nuts (AN365-428A), and 4 flat washers (AN960-416).

Fabricating Outside Bolts

  • Start by cutting two pieces of the threaded rod or steel rod 2-1/8 inches long.
  • Screw each piece of the threaded rod or slide each piece of the steel rod about half way into each of the two 5/8-18 nuts.
  • Weld around the nut where the rod passes into it, this will hold the rod in place.
    NOTE: If using the steel rod, make sure that it is at a 90 degree angle to the nut and not leaning to the side.
  • Once the stub is made, drill and tap a 1/4 inch hole into the end of the stub. This hole should be drilled from the end of the rod toward the nut. This will be used to bolt and to hold the outboard side of the wheel pant.

  • This stub will screw onto the end of the axle after the tire and lock nut are installed.

    Fabricating Inside Brace
  • Take the piece of 1/8 inch flat bar and cut two pieces 7 inches long.
  • Mark and drill one 1/4 inch hole in each end of the flat bar. The hole should be centered horizontally and about 3/4 inch from each end. This should leave 5-1/2 inches from the center of one hole to the center of the other hole.
  • You will then need to cut a small 1/2 moon shaped notch in the center of the flat bar on one side. This notch needs to be about 3/8 inch deep and should be curved enough to fit up against the 5/8 inch axle.

  • Once you have finished making the mount out of the flat bar, weld it to the inboard side of the flat washer on the axle cuff. The flat bar mount should be welded under the axle.

  • Fitting The Pants

  • Once the mounts have been made, you need to modify the wheel pants for mounting.
  • Locate the small indention on both sides of the wheel pant. The indention should be about 13-1/2 inches from the front of the pant and 2-3/8 inches from the bottom of the wheel pant. This indention is where the axle will go through the wheel pant. On the outside of the wheel pant, drill a 1/4 inch hole through this indention.
  • On the inboard side of the wheel pant, mark the two holes to mount it to the flat bar mount. The holes should be marked 2-3/4 inches from the center of the indention. The front hole should be about 2 inches from the bottom of the pant and the rear hole should be about 2-1/4 inches from the bottom. DO NOT drill these holes yet.
  • I made the cutout for the brake calipers to match the caliper. Cut it the width of the caliper and let it run all the way to the bottom of the wheel pant. You can see a picture of it on my site at www.anthonymcgee.com. Look under Challenger, then Modifications, then go to wheel pant mount The caliper will stick out of the mount about 1/4 inch or so.
  • Once the hole for the brake caliper is cut, trial fit the wheel pant on the axle cuff and see if it needs to be modified.
  • You may have to change the location of the inboard mount holes slightly to make the wheel pant level. Slight variances in the angle that the flat bar was welded to the axle could make this change.

  • Once you are sure of the location of the inboard holes, drill the 1/4 inch holes on the inboard side of the wheel pant.

  • Final Mounting Of The Wheel Pants

  • The wheel pant can now be mounted to the axle. The pant fits on the inboard side of the flat bar mount and on the outboard side of the stub. The pant is mounted using the AN4 bolts and flat washers. Place an AN970 flat washer between the bolt head and the wheel pant. Use BLUE Loctite to secure the bolt into the stub. Use the nyloc nuts and AN960 flat washers on the flat bar mount. Put the nuts inside the wheel pant with the bolt head on the outside of the wheel pant.
