Hey Bret,
Cool steering wheel. It reminds me a little of the center I have on one of the over the counter steering wheels I picked a while back.
I also have a few NOS adhesives that appear to be the same as the one you posted, but I'm not sure if they are identical. I picked them up from the John Atzbach collection, I was told they were originally from Chuck Cantwell. If you need a new one, just give me a ring Brother.
