    got the rear bumper all welded together. once that wa done i ground down all the welds then sanded the whole bumper with a da sander to blend everything really well. Also got it mocked up on the truck and tacked into place.

    only thing i don’t like is that the way the brackets to the frame are designed. they hit the back lip of the box on my setup. i’m not sure if all the trucks are this way or not. ill get some pics later. i ended up notching the bracket. the down side is that i will have to lift the box up about 1.5” in order to slide the bumper out. I figure it’s not a higher deal since i don’t plan on taking the bumper off too many time.

    Really nice fabricating, and it does look good.

    But I hope you're not planning on using it as a step anywhere but in the middle.

    got the front bumper all mocked up and tacked together. i ended up cutting the frame mounts a little and welding a plate to them. that way the frame mounts also tie into the B52 brackets. i have a warn m12000 on the way to try to get behind the bumper.

    now it’s time to weld everything up and spend a few hours grinding and sanding/blending everything together. also have to get the winch mounted and tow hooks welded on the bumper.

    That's got to be a heavy bumper. Stout for sure.

    the bumper is prob 100-120 lbs if i was to guess. the center is 1/4” thick and the outer part is 3/16. by the time i get the winch and tow hooks on it i would think that everything together would be around 250 lbs.

    had to do a little modification in order to get the bracket for the twin stick setup and the 205 case support to work together. I got the support clamped in the mill and notched the ring .25” deep so the corner of the twin stick cable bracket would fit.

    i had to pull the cab again today. in need to do some header fitting and get some broken manifold bolts out.

    here is how i did the manifold bolts in case any one is ever looming to do it.

    both bolts are brok off 1/8”-3/16” into the hole. i used my tig and some stainless rod to weld onto the broken bolt part and started stacking the bead up until i was about 1/8” past the head surface. once i was out that far i could put a stainless nut over the beads and tack weld it in place. I continued to fill the center of the nut while i welded it to the beads i had sticking out off the bolt. i let it cool down just a little and used some PB blaster while it was still hot so it would suck some into the threads as it finished cooling. then i just used a wrench and worked it back and forth a little until it came out.

    spent some time working on getting the warn m12000 winch tucked in behind the bumper. it’s a super tight fit since the winch is so large. i ended up swapping to a shorter motor (same hp though) and trimming up the frame a little to get everything tucked in place. should be a nice clean install when it’s finished up.

    got the front part of the stainless exhaust done on the truck. now i need to figure out a quiet muffler for it. i used the speed engineering short headers. the drivers side just needs a 45 and 90 bend to get it down to where i could run the pipe just in front of the pan. the passenger side i had to add in the header a little to get the v-band where i wanted it and the pipepointing the right direction. i built a merger for the 2.5” pipes from both sides into a single 3” also

    Nice build. Thanks for a proper 4x4 conversion. I'm planning on doing the same thing. I've built many rock crawlers and competition offroad vehicles, but this will be the first time I convert a road vehicle to four-wheel drive.
