Rear bumper mount upgrade

My rear bumper tire carrier was installed to the stock mounts, yikes! the sheet metal was torn. It was installed by a 4wd shop for the prior owner.

So I made some inserts into the frame rails using 2x4 square tube, 3/16th wall. on the gas filler side I used a shorter piece to clear the filler tube, but to get length I welded the square tube of 6 8nch length to a 1x2 inch channel, also 3/16th wall. the channel,is 14 inch long, and just fits under the gas filler tube.

On the end of the square tube I welded a 4 x7 inch 3/8 plate with 4 holes to receive the bumper.

Hopefully this will work fine. I did some test welds and used a 10 lbs sledge to try to break them, plate bent, so my welds should be plenty good

I also,installed shackle relocaters and integrated the mounting holes to my bumper mount. held on with 5 each 1/2 inch bolts per side thru the bottom of the frame rail. The bolts go into a half inch thick sold nut plate that slips above the channel, tapped with five holes each.

I did the same sort of thing 2x4x1/4 wall tube -- I notched the tube to slip under on the fuel fill side -- I also had to notch up from the bottom on the passenger side to clear a thick metal mounting tab on that side frame rail

Sounds like yours will hold just fine
