As a whole front end it should fit with some minor mods. I think there is one fender-to-core support bolt in a different spot and the way the bumper brackets attach to the frame rail is a little different but nothing that can't be overcome. There are some minor wiring alterations needed too.
It is not hard at all. I did it to my 74 Duster. Need a hood, grill, bumper, front valance, fenders, bumper mounts. and a few other odds and ends like the grill brace and wiering.
