Not knowing any of the race shops, I can only think of the old Dot Truck scales, on Wilkerson Blvd., at the River. Normally there's no one there, & they are a Short 1 piece scale. Probably 8'. I've weighed my pick up, & trailer on it, basically centering 1 axle at a time on it. Even unhooked my loaded trailer, to verify my tongue weight. I recon you could put 1 wheel at a time on it. Scale house is not open, but a pane of glass was left out, so you can turn the scale meter around towards you. It usually is anyways.
