Hello, I'm looking to buy a Plunger A10 frame and crankcase(would prefer rigid) and have to source the rest. I'm not worried about originality as long as it looks nice, But I would like to include some later parts in the Engine and Gearbox. Is it possible to fit a big bearing crank (I gather that is big Big ends) thick flange barrels and alloy head and box internals - or should I ask what won't fit?
Cheers
