The Stovebolt Site Forums The Shop Area General Truck Talk 1939 to 1946 Running Boards for a Pickup

39 and 40 running boards are the same. 41-46 running boards are different from 39-40. The splash apron is different from 39- 40 to accomodade for the wider fenders (39). I believe the 39 splash aprons are a 1 year only part, where the 1940 spash aprons are likely to interchange with the 41-46 years.
