I don't know if this subject has been discussed before, but has anyone listed the variations/evolutions in production of the cars over the years?
From my limited knowledge the differences between the TC and the TCS are:-
1) Possibly the addition of the front spoiler
2) The silver door sills
3) The rear gearbox mounting bracket and chassis shape V to U
4) The size of the rear brake drums and shoes
5) The brake shoe adjusters manual to automatic by hand brake movement.
6) 1/2" door hinge pins change from hollow to solid.
7) Fuel tank cap screw fit to flip top.
Can anyone add more differences?
During the production of the TCS 1973-1975, I have noticed only the following evolution:-
1) An aluminium plate by the radiator stopping rainwater running down the channel and dripping on the radiator fan.
2) Map compartment on the rear bulkhead between the seats.
3) Gas struts on the engine lid
4) Cloth seat inserts
5) At some time they changed the bracket for the clutch cable from chassis mounted to engine mounted to stop clutch judder from engine/chassis movement.
I have noticed the difference between US Federal Spec to UK Spec
1) Zenith/Stromberg carbs to Weber or Dellorto
2) Inset lights in the front and rear wings, (but the last of the UK spec cars used the Federal shells they had left).
3) Different cams for emission requirements
4) US spec cars had manual sliders on the dash to operate the heater direction controls.
5) US spec had 2 wipers, UK only 1.
6) Pipes from inlet to cast iron exhaust (no idea what they are called but presumably emission again.
7) Catch tank right across the engine bulkhead and catch tank by the left fuel tank (oil fumes? petrol fumes?)
US steering column mounted washer/wiper switch and electric pump, UK push pump on the dashboard
Other variations:-
1) Cast iron exhaust manifold and tubular steel 4 into 2 into 1.
Can anyone think of any other evolutions I have missed?
