I was at our local engine show in Wellington going through the flea market section, when I found what looked like the R.H.lower hood section for a KB7. There was another '46 KB7 on display on the other side of the fairgrounds, so I ran over there to make sure it was the same. Convinced that it was, I ran back to the guy and gave him 100.00 for this NOS part. I got it home, and... it's 1-1/2" too long! Does anybody know what this piece is supposed to fit on?
