Anybody looking for these..
Stainless Steel Bumpers - rvs - by owner - vehicle automotive sale (https://stlouis.craigslist.org/rvs/d/stainless-steel-bumpers/6199495586.html)
That is a good price, I'm just glad I don't need any. I pulled my rear bumper off a few years back to do some re alignment and there weren't but 3 of us to do the lifting. We got it done but 3 men is not enough for that weight. If I ever do it again it will be lifted differently.
They are not for a 91 model maybe earlier but not a 91.
My 89 has them.. I haven't a clue when FT quit using them.
