Hello fellow z fans I no longer own a z car and want to sell my left over bumper overriders.Im not clear what year these belong to so here are the demenions for the front bar. 31 3/4 long from tip to tip. the mounts are 27 3/4 from center hole's. The rear bar is 60'' wide outside mount holes are about 58'' center the 2 mount point at the center are 9 3/8 center of holes. they have been stored up in the rafters of my garage for the last 15 years and have a light coat of surface rust and grime. I cleaned a spot with chrome cleaner and it come off real easy. One of the center mount holes has a broken off bolt in it.
