your truck is what i'm after s far as motor and Box and look, did you shorten a LWB frame ? if so can you give me the measurements on the LWB & SWB & how much you shortened the frame ? what did you have to do to get the late model box on your frame as far as mounts ect. ? I was hoping to use the stock gas filler neck on the late model box and a frame mounted tank, there are some other good ideas on this thread 4 that too.
