So I've looked everywhere for the answer to this and can't find it. Even in the fifty something page post about why you should swap out stock hardware. Anyway my issue is I've bought all the bolts, washers, nuts that come in the Northridge 4x4 kit to swap out all my LCA and TB bolts. But I can't find info anywhere on the 14mm bolt and lock nut that their kit comes with for the 2012 JKs. Anybody know the length, shouldered/not, do I need washer/lock washer?

Here's what I've bought from the local store:
(4) Domestic 9/16‐18 X 3" Grade 8 Hex Head Cap Screw Yellow Zinc
(8) Domestic 9/16‐18 X 4" Grade 8 Hex Head Cap Screw Yellow Zinc
(12) 9/16‐18 Grade C All Metal Hex Lock Nut Zinc
(24) 9/16" Super 9 SAE (Type A Narrow) Flat Washer Yellow Zinc

All I need is the 14mm stuff for the front track bar frame side.
