Unknown Bumper, 1980s?

[Cadillac Nut]

I have been trying to identify this bumper for over a year.  It came in a lot of rechromed bumpers that I bought. My first thought was 1980s GM but it does not seem to match any 80s GM cars that I can find.  Could it be for a Toyota or some other import?   I don't even know if it's front or rear. Any help greatly appreciated.

looks like it is an 80's S-10 front bumper.

  It looks similar but still different, those bumpers look more flat from the photos I found of them, and the rubber strip is in a different position.  Also no "ridges" on top

1986 to 1991 Oldsmobile 88 rear. There is a part number break. 1986 to 1989, and 1990 and 1991.

Close but we haven't accounted for bolt slot adjacent to backup light opening.

As mentioned, '90 and '91 are a different part number from '86 to '89. This must be a '90 or '91, as the upper fascia wraps down from the top and is secured by a stud through that slot.

Ahhh thank you so much!  You know your stuff.  I tried for a long time to ID this bumper.
