Anyway, I've made my own version using Optima Mid front arms, hubs and carriers - I'll let the pic and videos do the rest of the talking.

Well I stuck in some electrics last night and gave her a test run today and wow! Exceeded all my expectations, it runs great! Thanks again to Mini Eason and Gomachv (Jeff) for the ideas

Pre-electrics:

Electrics used:
ESC: Novak Hammer Pro
Motor: Old 19 turn brushed
Servo: Low profile core
Battery: 4200mah shorty LiPo
Wheels: Avante Black Special Pink
Tyres: Vintage worn Schumacher CAT Full spike (1.9"?)
Whilst I'm waiting for my Sidewinder body to arrive I found an old unknown temporary orange body to use. Next I may remove the front Stealth and Dremel it to remove the top part as there is no topshaft used at the front, then fabricate a dust cover to keep the innards clean.
Hope you enjoy the videos

The video is in 2 parts as my daughter accidentally pressed the home button on my phone:
