The entire roof and half the quarter panel and the entire rocker panel is what is needed. The dutchmen panel is different too, and of course ALL the glass, then a pair of doors. I believe the "X" brace for the back seat is different also, and maybe the rear floor where the seat bottom fits, everything else is the same including the inner and outer wheel houses and trunk, of course the entire frame, and firewall also. Let me know if you need all that, I have a rolling back half of a 69 Swinger laying around, I wish I could have saved it being a 340 4-speed with factory A/C...
