I've searched the forums and don't see an answer to my question, so here goes...

I have a '66 C10 with a 250cid/MT and a 1BBL Rochester B. The throat of the carb is 2-1/8" and the bottom opening on my stock air cleaner is 2-5/8". There was a plastic adapter that sat on top of the carb, but I dropped it and it's bounced somewhere into another dimension. (Gotta be in the garage somewhere, but no luck after 3 days.)
I've been searching every vendor I can find on the 'net, Googled and checked out the swap meet in Sacramento this morning, but cannot find a source for that adapter.
I'm kind of a "keep 'er stock" Nazi.

Any ideas?
Thanks
