I agree 100% with Moparlee that is the Spring Special option for the '71 Challenger. It is a very rare piece to come by even all 3 pieces like you have there.Ive seen the two fender pieces for sale on E-bag before, but not the hood piece. Quite a find you have there. They were made of some type of chrome pot metal and pieces that were found were usually highly pitted. By the way the recess that runs horizontally on all 3 pieces was painted black. Thanks, Al
