Does anyone know if it is possible on a 1946 Chevy 1/2 ton to attach a pre-assembled front end to the truck or should I try to put it on piece by piece( fenders first then the rest)?? It seems almost impossible to align the fenders, 2 pc. grill, inner panels, filler pieces, lower valance and everything else if putting it together one at a time since there are dozens of screws and bolts. thanks mh
