Reproduction 71 rear bumper?

I'm having a hard time finding a replacement bumper and tail lights for the rear of my 71 dart swinger. I know the 70 model year rear bumper will bolt right up, but i'm torn between keeping it original or converting over to a 70 for lack of parts. After making a few phone calls to local shops it would cost 3 times more to have mine re-chromed as opposed to buying a new one and that still leaves me without tail lights as mine are in pretty rough shape. I was wondering if anyone could point me in the direction of a place where I could find a 71 reproduction rear bumper and tail lights before I pull the trigger on the 70 conversion.
