Argh.. These bearings won't fit the E-maxx gearbox!

I already gave up on this cause I couldn't find the right bearings for the job, but I thought I'd ask here before I throw them away;

I converted a T-maxx to E-maxx, but the diffs and outdrives are still the same. I tried to put the differential in an aluminium gearbox, but the bearings won't fit. I tried to order some E-maxx bearings but they don't fit either.

Now, the question is, are the diff. house and ring gear different than others? (The others which the bearings need to fit, along with the gearbox.) Will not other E-maxx bearings fit, and I need to do a custom fit?

Would appreciate some tips on how to approach this. Should I just buy an E-maxx diff. house and ring gear? Or does someone happen to know which bearings I need?
Also, this was the Maxx, not sure which one it is:
