conv. interior panels

I have a 68 B'cuda ragtop that is my good weather daily driver. I'm getting tired of listening to AM radio talk shows so it's time to upgrade the radio a little. I know it's a long shot but I'm going to look for some rear side panels that someone has already cut speaker holes into so I can swap them out and save my nice originals in case I decide to go back stock.
My question is, are the 67-69 Dart panels the same?
TIA,
Dallas
