dont i change my mind alot?

i know i change my mind alot, but i think i have something serious coming up.
a twin force, ditch the chain drive.
put a direct driven diff in it.
like you guys do with truggies and buggies.
i sketched up the motor/diff mount, but i need info.
without buying any thing, i'd like to figure out if it will work properly.
so i need to know the diameter and overall lenght outside on the bearings of a kyosho 1/8th diff.
also the size of the 44 and 46 plastic spurs.
i really need to figure out if there's enuff room under the center plate of the TF for the diff.
also on the gearing, will a motor like an lmt 1950 on 4s lipo run this beast without overheating? its gonna be geared in between 13.8 and 9.68, with 165 or 150 mm tires? would that work?
