Hello Jason,

Since you need the CE Smith Trailer Idler Hub Assembly w/ Case for 3.5K Axles - 5 on 4-1/2 - Galvanized - Pre-Greased # CE13515 you will want the #84 Spindle for 3,500-lb Trailer Axles - 1-3/4" Diameter # TRU64FR.

When swapping out a new spindle it needs to be precise. If you are not an experienced welder then I suggest having someone put it on for you. If you are experienced welder, then as Larry the Cable guy says, "Git-R-Done!"

Looks like you already knew the parts you needed, but just need someone to verify. What kind of boat trailer is this going on?
