Finer points of shortening and tucking bumpers?

['68 Newtricks]

I would like to shorten the front bumper.... and maybe the rear, not sure yet. I would also like to tuck it as close as possible. Anyone have any progress pictures of this being done? I like this picture below, would like to get my chrome bumper looking this sharp. Any tips? Chop frame horns? Wish upon a star?
