I figure, I'm gonna just replace the hardware while I'm at it. No reason not to, right?

Does anyone know what the bolt sizes are for the upper rear shock mounts?

What about the bolts for the leaf springs (the ones that go through the bushings)?

U-Bolts come with the kit, so I'm good there.

If I have to go have bolts made, I will do that, but I don't know the sizes.

 

5/16 shock bolts 1" long. The sping eye bolts are a dealer item im pretty sure.

 

There are 6 rear leaf springs bolts, M14x20x120 Flange Head Bolt.
My dealer wants $10 for a bolt, found regular Hex Head M14x20x120 with a couple of washers and they work great for $4 a bolt.
IIRC, there's some online store , that sell them as well....try google "jack-it".
