Mr Gasket Carburettor Bushing Kit
Fits GM & Holley Carburettors with 1/2" Throttle Hole

This Carburettor Bushing Kit reduces the 1/2" throttle shaft hole to 1/4" I.D., which makes for easy throttle linkage attachment, or can be used to replace the stock rubber unit. Machined from cold roll steel then bright zinc plated, the two piece bushing measures 9/16" wide when installed and fits most 4-bbl. carburettors with 1/2" throttle linkage hole.
