Thanks...I'm really after the rear bumper though, not the front. Mine was hit in the rear and needs the whole bumper assembly. It was hit the same way in 2011 and I went through the whole process of fixing it, then it got hit again! The '90-91 bumper cover is tough to find, but if I can use any bumper bar from '86-91, I have some opportunities to at least get that part. I know the bumper shocks are the same part number for all the years of this generation. The steel bar is a different number for '90-91 vs. '86-89, but I suspect the only difference is the two extra holes for mounting the later-style cover.
By the way, your Olds looks identical to mine, except mine is a '90. Same color and trim.
