Custom Dash Panel Brake Angle

1974 Dart Sport

I am looking into making my own dash insert that will be a complete piece from one side of the dash to the other using aluminum or something like it.

Want to have a metal shop put the brake in it and am wondering if anybody know the angle?

Also, does anybody have a template for the entire chunk of metal to make cutting easier...happy to pay for a copy of it.

Thanks!

Brian


Something like this pic but all one piece across......
