Triumph TR2-5 - Propshaft

Triumph TR2-5 - Propshaft
The engineers at Triumph were clever enough when they designed the TR2-6 series of sports cars to produce a gearbox that when fitted with overdrive was virtually the same length as the non-overdrive version.  This is an absolute bonus for spares stockists of propeller shafts as 'one size fits all'.  From a vehicle engineering point of view, it shows skill and understanding of the various options that could have been offered.
