67-69 Valiant 2 door interior panels

That seems to be the case. I've noticed that some vendors don't show any holes in the rear panels and in some of those cases, mention knockouts in the board for the required openings. Are there multiple knockout locations, i.e. one for hardtops and one for sedans? It would make sense to only use one backing board for multiple applications. I'll e-mail a couple of vendors and see what they've got to say about it.
