Wiring schematic for dash conversion
 

I am building a mild restomod and have a question/request or two. Firstly, I have a 65 2+2 A code and want to replace the dash with one from a 66 GT. If anyone has a diagram of the required wiring changes I would be greatful. Second, What width 15" rim will fit without chassis problems; and what tire size to use with modern radials?

cheers
Randy
