The Series 3 Land Rover has many Identification numbers stamped about the vehicle. Although these aren’t really required when ordering parts it is important to know what components are fitted to your vehicle in case they have been changed at some point in its life.  For example if you wanted a front inner hub bearing for your 1975 Series 3 but someone in the past had exchanged the front axle from one off a 1971 model then you might end up with the incorrect part as the bearing changed spec in 1972!

GEARBOX

Two types of Gearbox were used in Series III models. The original LT76 (LT for Leyland transmissions and 76 due to the 76mm between mainshaft and layshaft centres). And the LT95 as fitted to the V8 powered models.

Gearbox Numbers are usually found on the right hand side of the box about here.
