Realizing that each person has a preference of what looks good and this personal preference is why we like to see others projects. If all trucks stayed the same, looking at an original 1957 Chevy truck sales brochure would be all we would look at.
I have to agree with the original rear bumper not looking as good as it can. I've mentioned before, I didn't get the original so when I ordered the bumper and new brackets and mounted everything I was not happy with the fit.
I shortened and raised the brackets and made a filler panel. All original bumper parts, just fitted closer.
