please dont kill me, looking for rear leaf shackles

I made a set for mine, but they aren't any longer than stock. 5/16" plate and I can't remember if they are 5/16" or 3/8" grade 8 rear bolts...? I cut a stainless piece of tubing to sleeve the bushings so I wouldn't squish the **** out of the them when I tightened them up. Kinda hard to find 3" long shoulder bolts like what came from the factory.
