Need info on driveshaft thickness of JDM DC2R (36mm)

[hello]

1) is the thickness of driveshaft is the same with 32mm? (32mm nut size, shaft thickness is 25.5-26mm using vernier caliper)

2) does that mean the size of hub spline would also be different?

3) and the wheel bearing size between ek9(32mm) and jdm dc2r(36mm) would also be different i assume?

last) anyone able to tell me the jdm dc2r front wheel bearing part number?
ek9 is 44300-S5A-008

thanks for the help clubitr!
