The GM NOS Kingpin set on Ebay that I referenced is the correct part number. It is listed as the correct part number for 53-55 1st , 3/4,1 and 1 1/2 Ton.
I have a GM # 3704112 Kingpin set and the pins do measure .921" . I don't know where the .866" you referenced comes from. I understand that the GM Parts list text has 5 5/8 long x 15/16 O.D. ( .9375") but the pins in my set actually do measure .921. Hope this helps.
