I considered that possibility but if the engine were moved up front, it would also have to be changed from front drive to rear drive and I'm not sure how difficult that would be so I just moved it to the left side of the tank.Looking back a the photo on page 2 (interiour), would it be possible to move the engine to the front (shorter drive shaft), move the radiator to the side / or above the engine and strech the hull a little bit. You would have the driver / machine gunner on the left side behind each other and mayby room for six/eight soldiers in the back.
