Thank you for the question and all the feed back. We just got my 1 ton on the road (around town anyway). It has 3 on the floor with O.D. We're not sure if the O.D. works yet. Anyway, 35-40mph is about max speed at this point and we've started talking about what to do about the rear end gear ratio to get more apeed for out on the highway. Thank goodness for this site and Vintage Truck magazine, it also has helpful info. Bettyann
