HiYa Doug-
I'm just spitballin' here, but will dig out my Hundred Series MPC's and verify to be sure, then get back. I would say the 8N-804 pin was used on the 8N-802 Clevis Bracket. The NCA-804 pin would have come with the later modified clevis bracket and drawbar setup. They were two different animals, with the Hundred Series clevis and swinging drawbar being a better design. Here's why I say that. Every 8N and NAA came with the 8N-802 Clevis Bracket only on a new tractor. The Dearborn Swinging Drawbar used with it was a dealer optional accessory. There were at least three versions of the 8N bracket, having used a riveted unit, a welded assembly, and a stamped steel unit, with some variation of these in sequence. The 8N/NAA setup used the OEM 11-Hole Drawbar and Stay Bars with SAFETY WARNING BADGE/Check Chain assembly, all included in a parts shipping kit with each new tractor, and the optional Dearborn Swinging Drawbar see picture below. Now, with this setup, you cannot keep the swinging drawbar pinned in the clevis and then be able to use the 3-PT lift. When the 800 Models were introduced, Ford had revamped the clevis and drawbar design. It used a new clevis bracket & pin, a bracket that bolted to rear diffy case at the PTO, and a new drawbar. The original rear bracket was a riveted design, later changed to a welded assembly. This setup was a much improved design, and allowed the drawbar to be pinned in place when one desired to hitch an implement and use the 3-pt lift. For most implements, there is no need to remove the swinging drawbar. This is the setup that is sold today as an aftermarket kit. Still, many desire an OEM Dearborn Swinging Drawbar for their Ns and they pop up often. There is also CAD drawing in the NTC How-Tos for those with machining capabilities and a plasma cutter or CNC Mill. I will locate my MPC and delve deeper but I would surmise this to be the part differences.
