Help finding or constructing a new convertible top switch for my 68 Dart

We put a Barracuda dash in my son's Dart convertible. On the Barracudas the switch is kind of a tacky add-on to the underside of the dash, not a clean install like the Darts. We took the entire harness (with relays) and switch from a Le Baron. I installed the switch in the console ashtray. I will be doing the same in my Barracuda convertible.
