autobello CVT 4WD

so ive been working on an autobello with a cvt tramission and now that its working, i wanted to make it 4wd and thats where im stuck, even tho theres no front differential, im sure theres a way to make a functional powertrain setup whitout any 3d model ... or maybe not.

if its possible then how can it be done? any help to point me in the right direction is apreciated!

 

You need a front diff to make a 4wd setup, or, you could have electric 4wd, motors on the front, engine on the rear,
If you do add a front diff, you'll need the transfer case..

 

yeah i know i need a front diff, but the autobello doesnt have one, so how can i get this done,btw im trying to do all this without any 3d model, i just need a functional powertrain and selectable part , the only thing i was able to do is making the transfer case available in my cvt transmission as option.
