Brass - for those slightly more sympathetic drivers who prefer a faster shift.

The steel may require routine servicing every season. Both fit the original or our straight cut gears with no modifications. Fits any 4.2 all synchro gearbox.

Also the choice between the original large starter dog housing (for the original starter) or our slim line design (when using our modern pre-engaged starter) which helps to make it possible to remove the gearbox fromthe car leaving the engine in place.
