Rocketman:

Seeing as the openings in the T34 are rather limited, I'd suggest hiding it behind the driver's hatch. When you open the hull, you can unlock the catches, and from then on the hatch is only held closed by the friction of the hinge and gravity. You don't want to push a charge jack up into the turret, as its busy enough in there as it is., and pulling off the commander's cupola (after ya remove the single screw) is not as neat as hiding it behind the hull hatch.

Hope that helps...
