Hi,
nice project I would say. Congrats and welcome here, I just landed here too. My CA-Car has a custom trunk floor pan too, done by the previous owner. I would have used a reproduction one from AMD. But I have a repo trunk mat in now, and almost nobody sees the plain trunk floor.
Good luck with the Cuda. If I could, I would have one too... and a B-body or two.
