Shackle bolt size?

[greatguy57078]

I need a new bolt for the rear shackle. I can't for the life of me find the old one I removed. Can someone chime in and give me the right bolt size quick so I can stop at Fastenal and pick up a couple please? Much appreciated! ;D

1/2-13 x 4.5" or 5" will should do you just right.

spring side is 5/8 chassis side is 9/16. you want the shank to go through the whole thing

So....5 inch x 9/16" bolts? Yeah I need the chassis bolts. So...5" long?

off the top of my head 5" is too long. 4.5 is the one iirc

Grade 8?

I think its a 9/16-13. I noticed two weeks ago I was missing a nut on passenger side and the drivers side was loose. Went to my fav store and realized Lowes don't sell anything bigger than 1/2". Luckily I had another nut in the garage and slapped it on. I hope to get new shackle bushings for Xmas, but will replace the old bolts with new ones with nylon nuts fastened down.

Sorry I ran out and eyeballed the hole on a set of leaf springs. Thanks for bailing me out gang.

So I would assume Grade 8? %)
