None of those gears fit in the Eaton HO52 (or HO72) axle in your 1954 truck.

You could swap entire axle if you want. A 14 bolt dual rear from a "cab and chassis" truck is a good choice with single wheels installed. Some discussion in the tons of fun section about that swap.

Or as mentioned and explained in the tech tip 4.10 gears were at one time available for your original axle, and can still be found.
