Your truck is not a 1928. 1928 Chevy trucks had wood spoke wheels and no duals on the rear. The radiator shell is from a '29 or '30 car. Trucks had painted shells. It must be a '29-'32, which would have had a 194 c.i.d. inline 6 cylinder engine when new. If you have the hood side panels, they would help to visually identify your truck. If it has a factory I.D. tag, it will tell what you have. Chevrolet did not use a full floating rear axle on 1-1/2 ton trucks until 1936, so the rear end is 1936 or later. Only the early 1936 trucks had mechanical brakes. The change to hydraulic brakes came fairly early in the model year.
You can go to Google image and enter 1929 Chevy truck, then 1930 Chevy truck, etc until you find pics that match your rig. Good Luck.
