Make a good list for Fall Fling and get there EARLY. Like 5:30-6am and walk the line of swapper before you get in.
I got a bunch of A-body stuff at the last Spring Fling. And great deals. Hard to find stuff too like 68 GTS door emblems, all 4 67/68 Dart stainless wheel molding, 68 rocker spear, 68 headlight door, 340 block, RPM intake, etc etc...
73 Duster trim stuff shouldn't be too expensive if you hunt hard, just a matter of finding it.
