it will fit, the 4 of the the 6 holes along the bottom of the frame rails should line up. If your gonna go through that trouble though, you might as well get a 73-87 truck for 5 lug and disk brakes. its the same amount of work with more benefits. i picked up a 74 complete for 180 bucks and had the front crossmember bolted in under my 60 in just a couple late nights after work..
