Rear bumper for 1992 D150

I have the standard rear step bumper. I like the look of the standard non-step 1972 bumper but understand it won't fit a 92 model truck. Any way to bolt it to a 92? If so, anyone have a source for bumpers? Starting to build a parts stash for a restoration so lots of questions to follow. Thanks in advance for any help you can give.
