King Pin / Brake shaft issue

I'm rebuilding a front axle and started with good king pins so I just had new bushings installed and have the King Pins and spindles on the axle. The brake shafts were quite worn so new bushings were installed in the housing, and sized to fit new shafts. The problem is when I put the assembly into the King Pin, they won't turn. Its like the end of the shaft isn't the right shape to turn inside the King Pin. I even had a another set of King Pins laying around, different brand since they are marked L and R and still the same issue? It looks like I need to grind these to fit - is that normal?
 
Sounds like you may have the wrong kingpins or have them installed on the wrong side, which Tom already mentioned. Rod
 
Also, if you tried to stuff the felt INSIDE the kingpins, you need to remove it.
The felt fits between the end of the kingpin and the ledge on the backing plate.
I often have to slice the felt thinner to make it fit.
 
They are in the right way, nothing jammed in them. I have a set that is marked K-1010 R & L and the brake shafts fit fine in those. The only differences I can see are the set that I have that doesn't fit have a centering knob on the top and the inside portion where the brake shaft fits in is just too shallow to accomodate the head of the shaft. It hits on the inside. Are these bad repros? These were out of a rolling chassis that I bought. The King Pins that I have marked the K-1010 are in nice shape and fit the new bushings fine so I guess I'll just use those instead but I don't understand what's up with the other ones.
 
Ther K marking could be the Ford mark, which would make them 35-36 Ford. They will not work with the Model A brake pieces. Rod
 
I looks like the first set I was having issues with are B pins based on older posts and comparing angles.
 
Related question, since it looks I got a set of B Kingpins are the spindles the same on a B? I think that is where I got these, they were in a set of spindles I bought
 
These are B spindles.
