Frank, I included the #'s in the post above. . .or do you mean you cant find any numbers in research?

Dennis, what I meant is the number is 5715083 (LH), it's a Buick number and it's in the Gr. 10.?? section of the parts manual. When I ran the number here it shows it's in that section, but I don't see it. It could have been superceded early on or discontinued. Sometimes you have to look at the Illustrated manual to track stuff like that down.
ah. Ok, got it! ThanQ Frank! Perhaps someone out there can assist in identifying this gorgeous trim piece!? Wheelz, Tampa Bay
