King pins are out and the axle is prepped to send to SID to be modified!!

I had used the PDF below as a guide to pull these apart, but they were quite a bit different.

My spindles (out of a 1949 GMC) did not have retaining rings. Directly below the dust caps was the kingpin.
I pulled the dust caps and removed some of the excess grease in preperation to press the king pins out the next day at work, where I have access to a press. After I had them cleaned up, out of curiosity I grabbed a hammer and punch and gave the king pin a good whack. To my suprise it moved. 15-20 well placed whacks and the king pin hit the floor. Same with the other side.
Both sides were clearly well lubed, so I am sure this played a huge roll in there ease of removal.
How do I know f I need oversized Kingpins when I replace them?
