That is one nice 57. My first old truck was a 57 1/2 ton SWB. Back in 1973 I paid $100 for it and drove to work every day 65 miles oneway on shift work. Of course mine didn't look near as nice as that one. Lots of rust in the cab caused me to retire it after 2 years and put together a 56 to replace it with. I eventually replaced the 235 with a 283 and had lots of fun with that old truck. Larry
