  • I can't believe they would change the part number and make new drawings unless something changed. This is what I have so far:

    2N-16618 & 2N-16619 --> on the same drawing, dated 5/26/48
    8N-16618-A & 8N-16619 --> on the same drawing, dated 8/3/51
    9N-16618 & 9N-16619 --> on the same drawing, dated 7/6/43

    Wish I could find a '39 drawing, waiting to get these three in my hands.

  • Yep, some missing info for sure. Parts consisted of the initial technical drawing, a machining or stamping drawing, and an assembly drawing. Parts listed in the MPCS are almost always just the finished part assemblies. The MPC's won't list the basic part drawing number or the machining number. Lots of things need to be looked at when a part changed. The 2N radiator, grille, doglegs, front axle bolster and more are all intertwined. As parts changed, so did their individual components like mounting brackets. The doglegs are listed on the drawing as references. Lighting kits were available by late 1939. The March, 1940 MPC, the very first 9N parts catalog lists the lights near the back. MPC's were written/documented by the Ford lithography department months before they were issued. Lights were never OEM installed at the Rouge or later after the war, Highland Park on the N's. Kits were optional dealer accessories. Headlights didn't become standard equipment until the 800 Model. Thus, when the aluminum hoods were obsoleted, and the steel hoods came in, estimated to be around serial number 700/800, no one is really sure as no actual data can be found, did the aluminum doglegs also become obsolete then as well My guess is yes. I know my late '39 9N-653I has steel hood, steel doglegs with NO OEM PUNCHOUTS, and steel snap-in battery cover.

  • The manufacture process for a part may require mutiple steps and thus require multiple drawings. At both Ford and GM I made parts with multiple drawings needed for "sub-assemblies" that had to be combined by various means and were unuseable separately for service (field repairs) needs. A stamping may be an intermediate step and then welding on a bracket a second step. A single drawing may have been sufficient to make parts. Tim may chime in here.

  • Re: the Dog Leg discusstion
  • wish I had one of the drawing books. Now I am wondering why and when the mounting brackets changed. That might help explain why the dog legchanged. I do not have accurage information on when the light kits became available. They would not have a knock out for lights until Ford knew they were available. I do not think they did until '42 or '43
