I have just changed the engine and gearbox in the willy2 for a Williams 1 engine and gearbox. After various lassies, I've come to the last one hopefully. The passenger side driveshaft will not fit in to the gearbox, the tri sections seems too big. It fits the Williams 2 gearbox perfectly but not the Williams 1 gearbox.

1. Can anyone tell me if the the round type ends are different sizes,
and 2. Does anybody have a Williams 1 driveshaft for sale. Thanks. Steve
