body compatibilities?

i'm just wondering if its possible to fit the front fenders and hood onto the front of my 1971 datsun pickup? i dont care much for the shapes and design of my truck and im lookin for something with less ridges and maybe boxier look? im turning my truck into a mini..so any feedback would b greatly appreciated.id also like to find a more boxier bed thatll fit on my truck with out too much modification.
