What am I talkin' about???!!! I have "no more ideas". What a MORON I am!!!(yes...I said MORON!...see a particular other thread on this website to get the full gist of THAT statement, FOLKS...hint: it has "somethin' to do with HELMETS...although, you can also gain a little understanding of this "moron thing" on that LIGHT BULB thread TOO!!!)

FT, I THINK we might be in luck here. You see, I've just goggled "Buick Riviera Owner's Association" and talked to a guy named Ed who gave me the phone number for a guy who evidently specializes in Boattails. His name is Doug Seybold and his phone number is 1-440-835-1193. Ed said this guy has an ad in that B/R Owner's Club which says he has that part.
I called the number, but all I got was the ol' "leave a message" thing, and so I left my number and what you needed.
You may want to try calling that number yourself too.
