Rear leaf spring forward link bolt
I am trying to determine the pitch of the forward shackle 3/4 nut. This is the lower bolt as the top bolt does not have a nut. And yes this is not the center pivot bolt, as I believe that is much bigger. So I tried a 3/4 16, not sure if this is the one, snug to start. Help.

If the threads are rusty you will need to clean them up with a thread die. I have to clean up threads with taps & dies all the time when I am working on old cars & trucks.

I hate when that happens! In that case a thread die is the only chance to restore the threads.

Re: Rear leaf spring forward link bolt
speaking of these bolts - how much wear is too much wear? $40 a pop is quite hefty if I can get by...
Does anyone have any dimensions of these bolts?

AA Rear Spring Shackle Bolts
FYI
There were two styles of shackle bolts used for the AA rear springs. Attached are pictures. The square headed bolt was used starting April 1928 through May 1929. Otherwise, the hex. head bolt was used.

- AA's without emergency brakes used three bolts per side (upper and lower shackle bolts and rear upper seat bolt).

Re: Rear leaf spring forward link bolt
I've got several bolts that the threads are great and head is great but the shoulder is worn.
Would it be possible to lathe down the shoulder portion and slip a 1" OD bushing over it and JB weld or somehow secure the bushing from rotating?
1" bushings are much cheaper than $40 for a new bolt (i would need all 4...)

Re: Rear leaf spring forward link bolt
The shear strength would not be lessened by reducing the diameter to fit a bushing as long as it remained larger than the threaded portion.. Just freeze the bolt and heat the bushing with a .003" interference and there will be no rotating going on...
I'd rather have a used/new correct bolt...

If you're not planning on carrying a lot of weight, I imagine your method would work perfectly well. And, should it not work out, well......great topic for further discussion.
Go for it!

Re: Rear leaf spring forward link bolt
I think you need a one piece hard steel sleeve. If you have access to a lathe, you can make them.
