I only need them cause drilling them to 4.5 sealing axles shafts and dr diff said I needed the 4 drums drilled to use my currant brakes but is there a difference between the 10 5x4 and the 10 5x4.5 they’re both 2.5 shoes

Not sure what you're saying here- are you redrilling your stock axles, or using the Doctor Diff axles?
If you're using Doctor Diff's axles, you do NOT redrill your stock drums; you must use factory 5x4.5 brakes.
