Question about front bumper bolts on my 1929 phaeton
I am trying to find the bolts to attach the front bumper on my 1929 phaeton in my hoard of bolts. I thought I had some, but can't find them. Anyway, I dug out Mick Isbell's Ford Model A Standard Hardware booklet to see the type and size of bolts that are needed. His booklet says they are 1/2" -20 TPI 1 1/4" long hex bolts, PN A21219. This bolt size appears right. The bolt is specified on page 32 of his booklet. My question is, when you look at the picture of the bolt on page ix, it shows the bolt has a cotter pin hole in it. I don't remember the hole in the end of the bolts when I attached the bumper brackets on my 28 coupe several years ago. What gives? I am thinking this must be a mistake, as the nut shown below the bolt on page 32 is a standard hex nut, not a castellated nut that uses a cotter pin. I am attaching picture showing the bolt on page ix. Any helpful comments would be appreciated. If anyone has any of these bolt in good condition that they would sell, I could use some.
Thanks,
Rusty Nelson
