Used on my Chevrolet 66's carburetor with L6 and 1bbl carburetor. Fits perfectly. At first I thought I would have to shorten it, but the length was perfect.
Fits my Ford 2100 two-barrel carburettor, but it was too long! I had to use a hacksaw to cut about 2-3 inches from this stud. For the price it was worth it.
It is long so it can be trimmed. It's actually just a long solid threaded bolt with a wing nut. If I knew the size of the bobby pin I could go to the local hardware store and buy something cheaper.
