Need pic(s) and info of original rear sport bumper

[FirstOwner69]

There probably aren't many out there that are original since rear bumpers were an option and a large percentage had factory or aftermarket step bumpers. I am somewhat reluctant to post a picture of mine since the bumper, brackets and gravel shields are repros. However, since mine looks pretty close to the picture you posted, below is the best picture I can find of mine. I'm not near the truck to take measurements, but I'd estimate the top of the bumper is 3/8" to 1/2" below the taillight bezels and about about the same from the bed. I wouldn't be surprised if the actual factory mounting was slightly farther from the bed.
