How difficult to convert a 90 Daytona auto car to stick? I've got an A555, shifter and cables I could use as well as 87 pedals (not sure if they bolt up or not). I'm also wondering if I should go to an A523 instead of the A555 for smoother shifting (I find the A555 not the smoothest and I miss 3rd at times when I'm racing). I've used A520's and A555's, but never anything newer (A523 or A568). Any recommendations?
