On my A-bodies, the status is "will do". My 65 C-body has holes in the hood w/ square wire clips securing the seal. The original seal was just flat rubber 2.5"W x 37"L. Not much to show, just "punch hole in rubber and push clip thru".
My 65 Dart has similar holes in the hood. I don't know if I have the clips since I haven't replaced all the missing trim and parts that were in the trunk. I don't know what the original seal was, but I probably flat like my C-body, not L-shaped like in 604's photos. My 64 Valiant doesn't have any holes, and I don't see evidence someone filled them. Maybe they didn't have a radiator seal in 64. If I add one, I'll just secure w/ weatherstrip cement. No interest in fussy judges evaluating my cars at a show anyway.
