Keep in mind, the Dez is chassis #5 - ATV's changed the majority of the chassis and suspension since then
The new Tazcars have a 6 or 8 inch longer chassis & wheel base and the track width (wheel center to wheel center) may be a couple inches wider too - not positive about that, though.
Anyhow, here are the dimensions of the Dez:
OAL - 120"
OAW - 79"
Front Track - 68"
Rear Track - 70"
Wheelbase - 84"
