    here's a bolt that eluded me for years

        Yeah, there was one original bolt in my Tudor when I got it. And I thought to myself, bet that's the original bolt and all the others got dropped or shined off because they didn't want to have to deal with those fine threaded square nuts. Plus the tiny cotter pins. What about the hardware book? I'll have to look that up later tonight to see what it says about them and the finish. I copied pages from it when it was loaned to me but I never printed them out. I'll probably just pony up and order one someday beings I drool over things like that. I knew a contractor years ago that ran all Cat equipment and if any of his mechanics put anything but a Cat bolt on something he fired them.

          Is that the only cotter pin nut on the car that is not a castle nut?

            I think so. It's the only one I've ever come across.

            I need an original set of 8 for the pans on my 28.

                I found one at a swap meet recently. The guy gave it to me. So I'm up to 2 out of 6. Need 4 more. Anybody ever notice how hard it is to find 27-early 29 parts? I haven't seen one single drum light in 4 swap meets I've been to.

                  Dennis, there were atleast 3 drum tail lights at the Lincoln swap meet last March. Prices were OK, but none of them script so I passed on them. Rod

                    It's been 37 years since I've been to Lincoln, and unfortunately it wasn't a Model A swap meet. Just another grain elevator.

                      Jim, I picked up 5 of these this week from a friend that builds ratrods. Also 7 more shocks. Took him over 3 sides out of gas tanks to use to replace where the tanks he had were rusted out and 4 messed up shift levers. Rod

                        I also brought home a nice 28-29 headlight bar and an early 28 front fender bracket last month. Traded him a pair of cut off light bar ends and some front u-bolts and a few small common parts. Rod

                      Rod,
                      Those nuts "look" too thick,..I thought they were about .125" (1/8"),...also, I don't remember the lock washers for the cotter pin bolts. The pans that I repaired,..you could see the square
                      head left a "witness" mark in the pan...no lock washer mark! I did find one bolt and nut on a spare frame that I used as a pattern to make 4 1/2 sets for my Roadster, plus another car.

                        This is the way they were when I took them off of the frame along with what was left of the ears of the pans. Lock nuts were under the bolt heads and not the nuts. I was going to ask which other place on the A uses these lock nuts as I am missing one. But since they might not have been used on this application, guesse I will skip this question. Rod

                        A Parts Price List book from 1928 should give the dimensions for the engine pan bolts and nuts. I don't have mine handy, or I'd look it up.
