I can't recal ver seeing a 35-36 with a rear chrome bumper similar to a front.. I hope you know that the 35-bumper is similar to the '36, but very different.
I had a '37 Ford pickup many years ago that had a chrome rear bumper, as I recall it was the same as a front. I had harvested the bumper off of a '37 coupe.

The rear bumpers of a '36 do not bolt onto the side of the frame, they attach to the side of the frame as shown in the attached pix.
Look around for a '37 Ford pickup rear bumper bars, see if you can modify them to fit a '36 Ford bumper.

Ya know, a "Victor Wrench' can do wonders to make things fit.
