I did a conversion from the '71 RT to a base model for my brother. I filled in the side vents, cut the bulge out of the hood and filled it with plastic and made the center peak out of green stuff. The REALLY hard part of the conversion was the dash. It got a set of 60's on the back and a full set of Cragar SS wheels. He was ecstatic over the model when I gave it to him and it sits in a place of honor on his shelf.
