Checked the convertible that I have and all of them are rusted through. I will keep an eye out for a nice one for you (if you find one, make sure it comes with the extra reinforcement piece underneath). Mike
I have a Driver's side that was sold to me as a Fastback, but turns out it's not. Look at the pictures, as I'm not sure if there's a difference between the coupe and convertible. It's about as nice as you'll find, I think. I bead blasted it and marked a couple spots with a sharpie that will need some attention.
If you need one, it's yours for $50 plus shipping.
