Hi BBSD,
I think readers are slow to give you info because it is probably different across the board especially when you leave the 1/2 ton size, and use different pedals etc. This is a fabrication type deal which means everyone will probably do it a little differently. Mount the pedals, then if you have a rod, there is your measurement. If not, then mount the MS to the frame in a convenient location, within a reasonable distance from the pedal and make, find, buy an adjustable rod. I haven't done this yet on this year of truck, but will be on a 2 ton. I'm not concerned about mounting location. I'll be focused on the rod length when I'm done mounting things up. Just my two cents.
