Don't know what an OBS is but the bumper and brackets from a 92-96 should work
You need 92-96 f-150 or 92-98? F-250/350... I forget the body style change for the 3/4 ton 1 Ton... pre 92 (OSB) bumpers have a different frame horn, no crumple zone.Hi, I recently bought a '93 Bronco Custom that had no front bumper. I was wondering if an F-150 bumper from the OBS model years would slip on seamlessly?
