sabo: Ya, a LONG time ago! (15 years?). Now I'm unloading my collection of '09 parts, I'm finding their more valuable than thought!.
I was trying to find out ACCURATE info on 3 speed 09's, seems I was right about 64,maybe 63?, 62????. There were three 3 speeds, light duty, light duty w/od,and HD (possibly HD close ratio). Again, dealer order forms should tell what was required. As in "only available with" or "requires xxx".
