70 vs. G clutch components?????

[FactoryFarmer]

It's been a while since I've worked on a 70 gas but how much different are the drivers between these tractors? The 70s is flat if I remember correctly? I know the cranks are similar so the driver will fit fine on the crank but if
is there any difference in the belt pulleys?

With a steel flywheel on my G don't need the extra weight on the G driver throwing the assembly balance off.

Thanks

Pulleys and just about all internals are different.
G is 4 plate, 70 6.
