I know the hood scoops you are talking about. The ones that Plymouth used on the Cuda340 package and the Cuda383 package? I noticed Keith Marks has the decals for the hood stripes. I wouldn't think they would be all that hard to form and make.
Thanks Tim for your write up. I remember looking forward to building the Revell 70 Cuda after your write up. I also used your tips on your build to help me along the way. I am looking forward to you building this one.
