There are quite a few pics of the build in this thread. If you are looking for something specific, let me know and I will post it. I also have dimensions, part numbers, etc. of the materials.

nice job on the bumper, but one suggestion is that you could of brought the sides all the way back to the wheel well, but i think you did a good job i'm getting close to building up my bumpers
 
Here's another pic, then one of the FJ40 type license plate illuminator.

Hey I really like that bumper design,
Any measurements for it you'd be willing to give up to help me for my metalwork project at school?
Cheers Matt
 
Part list

Here are the parts to build the bumper and part of the swing arm. The main body of the bumper is 3/16 hot rolled steel. The top is 4 1/2 inches, the face is 4 inches, and the return is 4 inches at 45 degrees. The length of the main piece is 43 1/2 inches and the wings are 12 1/2 inches. The face on the end of the wings was tapered to 3 inches. This was bent up by a local metal fab shop. This shell is boxed with 3/16 flat stock.

The main supports off of the frame are 3/4 inch by 3 1/2 flat bar. I have been removing the 2 rear rivets off of the rear body to frame mount. I used 7/16 grade 8 bolts (4 each side) to attach the flat bar to the body. The other two bolt go where the original rear bumper to frame rivets were removed.

On Rigger's rig, we didn't want to alter the rear frame cross-member, so we mounted the flat bar to the outside of the frame. On others, I have mounted it to the inside of the frame.

Latch, swingarm, hardware, etc.

This is some of the hardware. The spindle is a standard 1 inch trailer axle spindle available from any trailer parts supplier. The bearings, cups, wheel seal, are all standard items. It is rated for 1000 lbs. (Spare tire with swingarm is around 125 lbs. ) The hub is machined out of some 1/2 inch thick dom tub. I have access to a metal lathe so I am able to do this myself.

The latch is a Destaco 5/16 with the safety latch. The spring pin is a t-handle version that it a little easier to get ahold of than some of the round knob versions. I installed a plate that the spring pin engages into when the swingarm is closed and also when it is open just over 90 degrees.

The small piece of angle is to back up the swing arm at the latch. Prevents the swingarm from going into you tailgate. I install some re-enforce rubber on the horizontal surface to help the swingarm stay put.

Swingarm

This is a shot of the swing arm. The swing arm is 2x3 rectangular steel. I have made them out of 3/16 and 1/4 inch thickness. I would stick with 3/16 unless you are going with dual jerry cans, cooler, hi-lift, etc.

The tire carrier is 1 3/4 DOM tubing, 1/8 wall. I bought a JD2 tubing bender so it gives me an excuse to use it. You could build the tire carrier out of rectangular tube.

Here's some odds and ends:

The swingarm on mine functions perfectly. It swings easily on those bearings. I don't think I installed that seal correctly, though. I may have pull the arm and inspect it. :doh:

The bearing cap is a nice touch.

I initially set the bumper so that the top surface was level, but I did not like the distance between the tire and the rear window. I wanted it in a little tighter; closer to the glass. So I loosened up the 8 bolts that hold the bumper to the frame and tilted the whole thing forward, then tightened it all up again. Now, the swingarm is sort of biased towards the truck, so it drifts closed if it is left open about 45 degrees or so.

The DeStaco latch is really nice; it functions well, and is adjustable for tightness.

The T-bar spring pin on mine is a bit sticky in the closed position. I like that, though, because I think it kinda discourages a passerby from messing with it.

That rubber pad that the swingarm closes against works great! I used gasket cement to stick it on.

The FJ40 license plate light is perfect. As Toyrod said, it keeps it all Toyota! It also happens to match the paint color of my truck.

The whole thing is solid, and the extra weight pushed the back end of the truck down a bit and alleviated the post-OME stinkbug look.

I'm very happy with the bumper, and I have received some nice compliments on it.

Thanks, Toyrod. Your fine work is appreciated.
 
Thanks alot for all the measurements Toyrod, that will help alot.
ill get started after i finish my sliders.
Might post up my version when its done to make yours look even better :doh:
Its the cleanest/most functional bumper ive seen and I want it :D
Cheers Matt
