first time builder needs input

[josh.backstrom]

the hard part of it all is all i have is a cab to start with. not being around these trucks much i dont know any of the dimensions of anything. so i start with the cab and then am going to build the rest of the truck around it. i made some first cuts last night so we will see where this will go. i got lots of plastic and body filler.............anything is possible. can someone give me dimensions on frame rails......there height, width, how far apart they are, approx how far they sit off the ground, and the minimum ground clearance i will need. any info is greatly appreciated. funds are non existant so im going to try to be very resourcefull and build a mock up frame out of wood
