RAWR!!!! What size bolt is supposed to go in the shock tower cap that hold down the prongs on the shocks?? I bought some more bolts and they don't fit either!

 

5/16"

 

A 5/16-18 X 7/8 hex head bolt with an external tooth lockwasher. If you use a bolt without a lockwasher, use a bolt that's one inch long and use a 5/16 flat washer and a 5/16 split ring lock washer to keep it there.
