The “new to me” cards where from another 68 barracuda that apparently received a nice new set. These required a little TLC as the vinyl had come loose along the bottom and a few clip holes had been damaged.
I used a sliver from western red cedar block. Tight grain, splits thin, real tough, and rot resistant. Then reconstructed the damaged card around the clip hole. I did 4 of these and used a heat gun to straighten the vinyl in a couple spots.
