Fart'n'go!
Here's a link to some Fargo truck history.

Us Canadians got lucky with Mercury trucks as well as Fargo trucks.
Here's a picture of my 56 Fargo COE. They were known as C series. Cab was used all the way till 1975 for large trucks. Pickup was similar from 55 thru early 60's. Grill changes in 57 and again in 58 to quad headlights.
