The Stovebolt Site Forums The Shop Area Driveline 1947-53 Rear Leaf Spring Shackles

I am re-using the cross pins in the rear shackles, but the small retaining pins are shot. Where can I get JUST the retaining pins?
-OR-
Is there an "updated" cross pin (bolt) that can be used, that doesn't use the retaining pins?

I was able to get one retaining bolt at NAPA after stripping a new one. I’m not sure if they were doing me a favor or if they have a part number for just the bolt.

When installing line up the spring pin best you can then set the lock bolt with a hammer and punch. Nut and lock washer are to keep it from falling out, the pin is soft and likely to strip if using nut to draw it into place.

I got some at Napa. Expensive and had to ship but they have them. May have an extra leftover if you confirm size. My suspension is mid 60s but maybe the same bolt.

Thanks! I live about 40 miles from the nearest NAPA.....I will have to check the next time I go that direction! I will check on the size, but they are APPROX 2 1/2" long, 3/8" diam, and have 1/4' threads....

I believe your're off a little on the dimensions, these rear spring and shackle pin lock bolts are same for 3/4 ton through 2 ton AD trucks.
The parts book shows them as 5/16-24 thread, which sounds familiar, and all but 2" long.

Like I said....APPROX......
I was just guessing, since I didn't have it in front of me.

Also, a couple of my shackles had gr8 bolts through instead of the tapered lock pins....They seemed to work for about 30 years, just wondering why they need to be the OEM lock pins....I have new pins now, but was just wondering...
