No, not all that much once you remove the turret.
Regarding the Yeramba. As I said I though a Sexton and said "That's too easy", but what really caught my eye was what looks like an open armoured filler cap slap bang in the middle of the glacis plate. What a place to put it, right where the enemy will most likely shoot! I've never seen that on any AFV, though the Covenanter with its glacis mounted radiators and shields come close.
