King pin?

I am looking for those little set screw type bolts that hold in king pins for rear leafs .I am not sure what they are called or if they are sold separate.I need them for my rear 56 chevy truck and dont want to have to buy new king pins when mine are fine .They just got damaged when I was hitting them out .
Anybody know where I can just get the screw ?

 

Huh?!?!?
King pins have nothing to do with rear suspension. You need to determine what the part you need is really called, cuz it ain't a king pin

Its the little pin in the number #3 LMC picture that holds the spring eye pin in .

 

so its part #4 or just order part 3 as a kit. seems cheap enough.

 

Its a little tapered bolt that holds the front of the rear leafs on the truck frame .I see the item it holds on is called rear spring eye pin but I dont know what that tapered little bolt that holds it on is called .My pins are perfect just need that little locking deal .
I just need the one tiny bolt seems dumb to pay $60 bucks for two of the whole units just to get that one little locking one .

 

#4 is just the pin and my pins are perfect I just need the little one in pic#3 with the kit that the nut threads on to .

 

I need the highlighted green one in this pic .I guess its called lock pin but that such a vague name that tons of stuff comes up .My question is if anybody knows where I can just get those .

That's weird, never seen those before. They look a lot like 49-54 Chevy front king pin sets. Learned something today.

Yeah and the wedge in tight so when you take them out they usually get damaged .

If a guy had a lathe, he could make his own.

 

Thats them but for that price I might as well just order the whole one on LMC .I was hoping the pins be like couple bucks each.Made a offer though thanks

 

is this the same? http://www.ebay.com/itm/56-67-Chevr...Bolt-NOS-3656671-/370606577255#ht_1700wt_1030

 

that guy is nuts on price,make him a offer !

 

Looks to be the same

 

I was mainly showing you the part number, and letting everyone else see what they look like. Search..you might find some for a reasonable price, or you might not.

thanks for the number. don't have that manual.

 

that's almost reasonable.

 

Its reasonable if they're made in the US and not some Chinese monkey metal junk. For myself, if the seller couldn't verify that they're made somewhere where you can trust the quality and metallurgy, then I'd pay the $40 for the NOS pair before paying $20 for a pair of unknown origin since, judging from the assembly pic, that's a sorta critical application.
