Tim - on every TF truck I've seen [or rather, bothered to notice], the stamp was on the drivers frame rail top web just about over the axle, pretty easy to see once the usual fog of grease/road sludge is gone .... that's been at least 6 '56-'58 trucks, don't recall the few 55.2's I've seen and don't think I've ever looked over any '59's .... that pic is from a friends '56 panel that has had power steering installed
