1st gen 4Runner rear tube bumper build
Here's a rear tube bumper I built for my 84 4Runner. Just a sidenote, I've cut my stock 4Runner tailgate off in place for a truck tailgate.

Started with a heavy duty crossmember. 2" x 3" square tubing fits perfect in the frame rails (with a little BFH action). Welded it in hot.

Tied it into the existing crossmember that used to hold the spare tire carrier using some 2"x2" .120 wall stuff I had laying around.

Adding some corner gussets as well to help with those heavy tugs

Sometimes you just have to find the "right" combo of stuff to help hold your stuff level

Trimmed the tube in the front to match the rear of the wheelwell.

Here's what the sides will look like.

Here's the rest of the bumper. I'll need to notch and cut them and they'll be ready to weld in.

Frame tie-in for the front part of the bumper

Used a 1/4" scab plate on the frame.

The hitch pin hole is close to the rear tube but should work

Bumper support tube to rear crossmember. No scab plate needed since the crossmember is 1/4" thick.

Rear reciever hitch tubing welded to crossmember. I'll add a gusset to the bottom.
