47-55.1 Kingpin/spindle bushing question

[Frankthetank.]

So I’m rebuilding the kingpins on my 52, I bought a kit from speedway that says it’s for 47-59 1/2 ton truck. Everything was fine till I took apart the driver side. It had what I’m assuming is a factory bearing between the bottom of the spindle & the axle.

The kit I got from speedway does not have this bearing & I doubt I’m expected to use the original. I also read in one of the questions asked by another buyer that had the same issue, speedway says that someone must of stuck that bearing in there cause it’s correct for the Chevy cars but not the trucks.

I broke out the 47-54 assembly manual but I do not think it covers the axle at least not that I noticed.

Can anyone that’s rebuilt one of these verify that the 47-53 take a bearing?
