It's Roy Nacewicz he's the one that makes all of the original type nuts and Bolts and other things for that person who wants to make there Model A's a show car.
That's where most if not all of the suppliers get there supply's from as he is the only one that I know of that makes the original type supplies for the Model A's today and you can actually buy from him also and his on-line catalog web site is
www.fordscript.com.
