What is the correct stack-up of hardware on the windshield hold open stud?
I have assembled mine in this order and it works fine. Most important is that the Belleville washer goes immediately before the nut. Depending on the alignment of the arm to the flat on the fixed post (which is determined by the position of the windshield in its top hinge), you may need additional flat washers stacked to the outside of the swing arm to enable the swing arm to travel freely. I've also found that the rubber washers vary in thickness, with some so thin that they don't protrude outside of their cups. So you may need to stack another flat washer inside of the cup to get the rubber to protrude.This is from Bratton's online catalog. https://www.brattons.com/SWING-ARM-NUT-WASHERS/productinfo/30140/ This is the way I have mine. I can't tell if you have the flat washer.

Is this the correct assembly and is it correct for 1928 thru 1931?![]()
I think either could be correct depending upon which side you think you are showing, and where the windshield is. There is only one way that the swing arm will fit into position so that it folds up parallel to the windshield as the windshield closes. Post #5 would be correct for the right side, looking from the outside through the windshield. Post 7 would be correct or the left side looking from the inside out.I have done more research using old dealer's catalogs and the Ford Body Parts List of April 1932. My sketch in Post 5 I do not believe is correct. For example, the swing arm in Post 5 is backwards. The sketch attached to this post makes more sense to me.
I find there are 4 basic configurations of the windshield swing arm assembly, one for the 60-A & 60-B Briggs Leather-Back Fordors, one for the remainder of 1928-'29, one for 1930-'31 straight windshield vehicle and one for 1931 slant windshield cars.
Once I get confirmation or corrections to the sketch below, I will detail it with part numbers and post it here again.
removedThis is my presentation slide & I hope it is correct. I find that this aspect of the Model A has been overlooked, so that is my motivation for this slide.
The wave washer goes where the swing arm attaches to the windshield frame. It's there to stop rattles not as a lock washer. I don't think the lock washer shown there on the oval head screw (message 9) should be there as that is a rotating point and the screw should just bottom out in the frame leaving it free to rotate.Post #5 looks correct to me and that is how I have it configured on my A. It only makes sense that the spring washer would be between the big nut and the steel/rubber washer to hold the nut tight..
