I second Paul's comments that the Inner Fenders (aprons) are different. They carry different part numbers in all 35/36 parts listings. 50-16082/83 for pickup/panel delivery and 51-16082/83 for large truck.There is a big dimensional difference between 1/2 ton commercial inner fenders and the big truck. 1935-36 share and 1937 is by itself, pickup or big truck. Contact screen name "oldandtired" he is on top of 1935,1936 and 1937 Pickup and truck parts and differences.
