Not sure what pictures youre looking at, I have also adapted some big Spicer axles, that might be what you're seeing.


The P30 spindles to 2 ton axle works as I describe, have a set of nested stock P30 and 2 ton bushings here on the bench in P30 spindles.
Kingpin is 6.344" long for both 2 ton and P-30.
