I am looking for belt line molding and 1/4 window trim for my 89 Custom Cruiser. I also need the impact strip for the rear bumper.
Having the same challenge with our 87 Pontiac Safari. Found belt weatherstrip/ window scrape seals at Rockauto.com which should fit all the GM wagons of that era. When local body shop (resto specialists) went to install they found fitting issues. The upward beltline curvature at the front of the front door differed from the curvature of replacement part. Now sending parts back and continuing to look for nos online. Saw front and rear impact strips on ebay a few days ago but believe it was for Chevy so not sure if it would fit your Olds even if still available. Our problem may be that there are some subtle differences between the divisions and parts are being made for Chevys and sold as good for Buick-Olds-Pontiac also.
I sent you a PM. Can you post a picture of the spot you're trying to get trim for, as well as the trim that you do have please? Thanks!
I have Mitchells body manual and they show different factory part numbers for varying years for the Olds. 89 /90 parts have same part # but earlier years show a different part#. There are subtle differences according to the book. dimensions are different year to year.
Impact strip is super hard to find. You could buy one from an 90s S10 and modify it. https://www.partsgeek.com/nnyb23m-c...&fp=pp&utm_term=Chevrolet+Bumper+Impact+Strip
Here is photo of replacement trim that has wrong curvature. We had it removed and just had the original with bad rubber replaced.
