I've got a 1939 3/4 Ton Stake Chevy. It has the pans. There were numerous names for them. You rarely see them on the trucks. They were referred to as Engine Pans, Engine Side Pans, Engine Side Splash Pans, Engine Splash Pans. I sold an extra set last fall. I'm not sure but I believe the right side pan would be very similar from 1939-1946. The drivers side would be different due to the location of the hole for the exhaust pipe. I could take pictures of my right side one, take measurements, and possibly you could manufacture your own. Rick G.
