57 would have been in the "fridge" era body style,
Like this?
57's the first year of the "fridge" body style, first year for the "style side" bed, first year 4WD was offered from the factory although Ford farmed the conversion out, and the only year the "fridge" came with single headlights. The original "High Boy".
Don't ask me how I know all this mundane trivia.
Yep, just like that.
A young guy not far from me has a 2wd sort bed fridge for sale. $2200 asking price, runs and drives, Y block V8... lots to work with, I think it's a 59.
