This can be a frustrating job.... As the oldest fossil in our shop, it has
come to me (since I used to work on KPs when they were on new pick ups). Add
that king pins can fool you.... one will come so easy it seeems like it fell
out and the next will tax even all of the old tricks I have learned. - on a
scale of 1 to 10, the difficult ones come in at about 14.5 since the damage
inexperience can leave behind can reach astronomic levels.

I suggest finding an old timer that can do it as econimcally as possible. If
you are in for the game, eyeball what you have (including looseness,
difficulty turning the knuckle and anything else that can give insight) and
post back here.... It may take time for a reply, but I can try to help.

Sometimes those pins can be difficult to say the least.  I
have change some that only took a couple of taps with a 4lb
hammer and a brass drift to popp out.  I changed the ones in
my Dad's old '69 a while back.  This was the first
replacement for it and they had always been maintained.
After they did not move with heat and the hammer, I took the
axles out and took them down the the welding shop.  We set
them up in his 90 ton press.  They pushed out just over 60
tons.  I would never have been able to get them out w/o the
press.  He charged me $20 to remove the old ones and another
$20 to install and ream the new bushings.  A well spent $40.

Good luck
