Your bearing blocks appear to be these ones - https://content.vexrobotics.com/vexp...40122-Rev2.PDF

I could be mistaken, but it appears that when they are flipped (so the flat side on top) the central hole is 1/8" higher than when they are not flipped. This would give you a drop center to reduce scrub force when turning.

Yours appear to be the other way around.

What do the gearboxes mount to? Do you have some sort of bellypan? Central stiffening?

I'm generally confused because there isn't a lot in your drawing and I'm not sure where you want help.
