I had considered that, but it doesn't look even close to the rear window seal that was included with the lot (which I know is the correct one.) And it just has too many "slots" for anything I can think of. I checked again with the seller and he's sure this was ordered for his truck -- he's only got one project and the stuff was all kept together in the same box since it was delivered. Heaven forbid he have the original packing list, of course. Oh, well. Thanks for looking and thinking! smile
