Yeah, the AE electric spurs are 48dp. It's easier to find pinion gears in this size, that's why I said you can use them.
I completely removed the brake assembly!! No need for it. The motor mount goes to the tranny at the two points where the brake assembly mounted. The front end of the mount is also attached to the chassis to stiffen things up, but it's not a flexy truck by any means to begin with.
It is a pretty good alternative as long as you don't mind making battery trays n such.
