Nice...Glad to see he chose a C11G 4 speed box (which is the same as the plunger A10 box internally, apart from the main shaft) rather than the 'mangle' gearbox from the M20..
The 'camplate' design of the C Series box is comparable to the swinging arm box for ease of gear changing and on a par with more modern gearboxes....
It would take him at least twice as long to select four gears and neutral statically with an M20 box... ...Ian
