Different animals
After reading some previous threads, it looks like roof skins from '67 thru '74 are all the same, given that both cars are 2-door.
Were there any post Darts during that period? I thought they were all either hardtops or convertibles.
Not necessarily!
If they're both 2 door hardtops, the skins are the same. "Post" cars like paulys valiant are different though.
