*** IN STOCK SHIPS TODAY *** RBS carries a complete supply of parts to service Donovan gear drives to keep the racer out on the track and winning rounds. From time to time the need will arise to change the gear drive to another engine block and somehow this is one of those parts that no one knows how gets lost in the transition.
Well friends RBS is here to help with this bronze BBC cam shim. Fits all Donovan BBC gear drives behind the cam hub and the engine block. Bronze shim is 2.940" O.D., 1.970" I.D. and .032" thick.
