Hanno,
With your picture on screen,I took the back off the 15CWT,actually it's not glued on right now,owing to my darling wife's dusting the wall unit.There's not much trouble in the way of building up a new rear deck extension.The rear of the cab wall is no problem or interference.The only question,not visible in your attendant photo which I cannot see,is,where does the spare tire & holder go?Perhaps on the side behind the driver?
Also,receiving my(finally after 10 weeks because it is rare to purchase)M4A2 Sherman which,with the ultracast decals,will become a 1/35th replica of "Bomb"including the writing on the right side with the grenade image.If you take the Chevy FAT cab less roof and doors & combine the 15CWT rear,it is easily converted using plastic sprue.Good luck & let us know.With real CMP's becoming rare,we Canucks & you guys in Europe will make Tamiya & Italeri very rich.
