Just to clarify guys, im wanting to put a 70's cab and bed on a 80's chassis, and i measured the 1984 F350 IDI, but the 1970 F250 is in Ohio, a ways away from me, so ive been trying to find diagrams or websites that mite have the measurements of the body and chassis that way. i havent bought anything yet, trying to do my research first. again anything anyone knows about this is greatly appreciated guys, thanks
