Thanks fellas.
The tracked Grizzly is on a 6-roadwheel M-113 lower. The 113 hull was split between the 2 & 3 wheels, and will have be spaced to accommodate a new wheel station. The hull was also split about halfway up horizontally. The lower glacis angle will carry upwards from the lower hull to the AVGP upper. Imagine a Warrior MCV with a 1m turret, and that's pretty much what it's going to look like. Might even put some add on armour like the Warrior has. So far, its been a pretty straightforward cut as the width is an OOB match, and so is the M113 ramp arch a direct match to the rear door arch on the AVGP.
