kingisomer,
Thanks! That helps a lot. My bolt is actually about 3.5 inches long, but looks identical in all other respects. I suspect the difference in length is that mine is on a 1.5-ton chassis. Prob. bigger truck with a bigger frame requires a longer bolt.
I found two regular nuts in my "pile",but just assumed with the cotter pin hole it would use a castle nut. I guess that's not necessary! I didn't know until I started looking for them, that 7/16th bolts are such an odd size. (can't find 'em in the local hardware store, or even Home Depot/Lowes). Glad I found mine!
