NO - I wouldn't want to sell my Comet anyway! I would maybe just want to make it more like a GT in style - more sporty.
There are at least two different ones that I know of. My 73 has the ones that come to a point at the front and I think yours are squared front and back. The GT is also in different places I think. Mine are at the back.
