pittman arm length Schroeder manual steering
 

Folks,

We're going to run a vintage Watson-Chevy Champ Car in a vintage race for formula cars on a road course. Anyone have a baseline starting point for pittman arm length? What might've been used in the day at, say, Phoenix or Trenton (paved)?

The road course is a lot like the old IRP road course -- long straights, pretty good speeds. Any help appreciated.

Thanks,
