1950 dodge b2b king pin question...

Hey everyone,

I found a guy who has a dropped axle for my truck but he asked if I had the small or big king pins and I'm not sure. He said if I had the big ones he can drill out the holes to match them but I'm not sure which ones I have. Does anyone know what size the king pin is? It's a 1950 dodge b2b pickup.

Thanks!!

Matt

 

Maybe a ford or Chevy has the same size? Just need to know the size of the kingpin.

Thanks

Matt
