Patch Panels

I am looking for patch panels for my 66 Coronet. I need the Passenger side quarter, frong and rear of wheel well, door front corner and rear corner, trunk pans and drivers side front of wheel well.

Any ideas or suppliers?

On my 67 I made my own. They are relatively flat and didn't take much to make them out of some sheet metal from a a local heating supply shop. Used galveneel and not galvenized as it will hold paint.
