Rear Bumper with Tire Carrier

By: cbbr

My rear bumper is 2×4 and 2×2 3/16 with 10 guage sheet metal. The tire carrier is 2×4 3/16 held on with a 1″ x 10″ grade 8. The bolt has 2 contact points and passes through 4 sections of the 3/16. There is a grade 8 nut welded in near the bottom. I also ran a seam down the path so that the bolt threads all the way down and used flanged bronze bushings to keep things smooth. The other side is a 9/16 grade 8 and another nut welded in.

The sides of the rear are 3/16″ square tube, capped and angled in the front and then skinned in the 10 gauge sheet metal. They follow the original rub strip.

The whole thing is mounted to a set of CUCV mounts with lots of 9/16″ grade 8′s and has CUCV clevis rings.

The gas cans are NATO 5 gals and the mount is 3/16″ angle iron. I boxed in an original Chevy license plate mount so thatI could retain the light for inspection purposes.
I custom made the hinge with 2 shear points after seeing and reading about tire carriers using the aftermarket hinges breaking.  I believe that my design is far stronger because of both materials and the double shear point.
