The cab will drop down at the up slope body line. The only way to make it look right in my eyes. I could Move that body line back some if I need more room for seats and a gun rack. The 5 window look is era correct and looks cool it has crossed my mind but is alot of work just for looks but then the whole project is.
If I was better with computers I'd try to make a digital picture of what looks right but posting on hear is a stretch. I'm thinking 110-115" wheel base is about right and leaf springs I think yj springs front and 56" chevy springs in back with the shackle right at the rear bumper. Likely 5-7" of lift and 35s I may run a 38-11 bogger at some point but Un likely. I want this clean and drivable so my superduty can sit.
