63 Dart convertible attaching the top

Exactly right! Got it outside and found the holes matched up so its now on there. Does anyone know where I might find a template for the top well liner? Mine is toast, brittle as uh, uh peanut brittle! yeah that's it peanut brittle!
I know I c an buy a new one for $200+ but my car has been repainted and not the original color so I thought if I could find a template I might try sewing one myself.
Thanks y'all.
