Only problem with coupe Decor Group panels back there is they had armrests. If you're buying repros, specify that you don't want the vinyl punched. Maybe they're not punched, I don't know; I've only dealt with NOS or mint used for those, not the repro ones.
If you don't care if the panels are correct for a HT, look for someone parting a Belvedere or RR coupe, either '68 or '69. Same pattern. Rear armrests were optional, so check that.
