Here's my front stubby bumper.
I cut the plate out, and drilled holes in all the corners of the cut-outs. I then connected the "dots" with a zip disc on a grinder, then made it look nice with a die-grinder. Big pain in the ***, but it's worth it for the pretty holes.
I had it all tacked together for a test fit.
Ok, fits good! Took it off to weld it, and put it on the jeep again to use a bumper until I work on it again.
Made the clevis tabs out of 1" thick QT100 plate, drilled 1" holes in them and welded them on, and welded up the whole bumper. I then spent a bunch of time cleaning up all the welds and spatter.
All done now but the paint and the 4 holes for the winch mount. The top plate that the winch mounts to is 1/4", the fairlead mount and formed bottom is all 3/16". There are also 1/4" doubler plates inside, opposite to where the clevis mounts are welded on for extra assurance.
The winch plate is not removable obviously, which means you have to remove the bumper to get the winch off. This is by design so it doesn't get stolen.
