Thanks for sending in your picture and a tape measurement of a 1-7/8" dust cap, but we don't have any dust covers with an outer diameter of 1.875". We have a bearing protector that is 1.78" in outer diameter, which is the Fulton Grease Cap - 1.786" Outer Diameter # F001503.The next size up is a 1.988" dust cap # RG04-020.

It's also possible that the hubs on your 1947 International KB-1 Truck have non-standard sizes. I highly recommend picking up a digital caliper like # PTW80157 to get an extra precise measurement to make sure you're getting the best fit for your truck.
