I suspect the Pontiac front clip is similar to the Nova, Camero, Cutlass clips. Done quite frequently and with good results. However, as easy as it is, the possibility of a hack job looms high. If you can’t personally inspect it or have a trusted 3rd party to inspect it you would be money ahead to pass on this one.
