Bumber Swap

No I don't. But I have done a little looking in to it on my 75 Duster that I am changing over to look like a 71 Demon.

I think if you bolt the bumper mounts to the bumper then hold it in place on the car with som blocks or rope or some thing where it needs to go. Then go under there and mark the holes where the bumper brackets will bolt on to the car. Take the bumper off drill the holes then mount the bumper on with some nuts and bolts. Should not be all that hard I don't think.

On thig is on the sides of the bumper there is going to be a slight gap at the 1/4 panels as the later cars had that filler strip to hide that area. But it should be easy to weld a peice of sheet metal in there to hide the gap.
