A new OEM General Motors King Pin Set that I got at an auction of vintage car parts.  This is part no. 2321010.

From what I could find, this is for all GMC Truck 100-900 Models; S, T, X, and Y Series; with the F070 Axle except for P350 Trucks.  I don't know what years this covers.

This looks like it has all the parts for a normal king pin set, but the box was open when I got this so there may be some small parts missing.
