RCM V1 revo hybrid diff

I start to build it today, and when i want to install the center drive shaft yoke on the diff pinion, the hole in the mod pinion don't align with the hole on the yoke.
Have you experiment the same prob with your diff?

I can't push the yoke far enough to align the holes togheter. Like if the flat spot on the mod pinion is not long enough.

the only thing that i see is to remove some plastic on the yoke to push it farther on the pinion gear.
