Ford Blitz Restoration/Rebuild for easy reference:
- 81T 3115 is the part number for just the king pin (listed as "Bolt-spindle") with a length of 7.10
- 81T 3123A is the "Bearing-spindle bolt (Timken #T113 and Nice #5883)"
- 81T 3111 is the part number for king pin kit, 2 pins and all the necessary parts, these fit the following: Ford trucks 1938-1947 all 1-1/2 ton models except 122" wheelbase.
