Sorry boys, junkyard was a bust, I did manage to snag some 1970 dart taillights I’ve been needing and a few pieces of odds and ends but the list of BOLO objects including the valence I went for, turned out to be an 0-fer.
You tried, that's good. I searched out and found a listing for a 64 Valiant trunk lid, guy responded this a.m., had already sold (for OMR). No Canadian 64 Valiants found for tail panel pieces either
