Looking at your pictures, I noticed it looks like your front axle has bolt on dust caps. 2 ton axles were like that. The 1 1/2 ton axles used a screw type dust cap. 1 1/2 ton, & 2 ton trucks had different size lug studs, in most cases. Last time I needed new studs I looked up the original part number out of the Master Parts Catalog, & used Parts Voice to find the original studs on a Chevrolet Dealer shelf. The Master Parts Catalog also gives the stud dimensions.
