Carburetor dash pot bracket, this is the bracket with a 'hump' and a hole. Fits all Autolite 2100, 4100, and 4300 carburetors if needed 1967-68 Mercury Cougar and 1965-68 Ford and Mustang. Some of these have a trace of Gold color on them like other carburetor parts. Small hole for attaching to left front of the carburetors, before anyone asks, we do not have the fasteners for these. Larger hole is threaded for factory installed dashpot which is 5/16-24. Some, or most carburetors likely had these from the factory, with automatic transmissions. The small hole near the 'hump' was used a return spring on full sized cars with kick down rods.
