Mike I thought you were now doing a Mk2 carrier so you shouldn't have a radio battery box on the back. Your radio box sits beside the driver just to his right. It was designed to perfectly hit your elbow every time.
I can picture in my mind a few years from now your carring driving around with a bunch of big guys in it wearing bearskin head dress and drinking beer with a few chickens in cages straped to the back along with double barreled paint guns to shoot trouble makers and you will be singing a wierd drunken compilation of rev war/ and WW2 and some french songs thrown in for a good mix. I can't wait but at least you guys will be having fun because thats what its all about
