Leaf Spring Bolt Size?

Does anybody know the exact size and threads for the main leaf spring bolt?I'm on the other side of town from where I live and I need to buy a tap and die of that size over here before going home. There was a thread on this recently but I haven't been able to find it so far and I don't think anybody had a definitive answer. TIA.

Edit: It was a JU Thread I was thinking of but the answer was never posted.

Called the dealership parts department, they don't know either. Anybody? Somebody have an online FSM? Would that even have the bolt specs?

It's 14mm. Sorry, I don't know the thread pitch.

Thanks, that should narrow it down enough, there are only a few thread pitch's available IIRC.

For everybody's future reference, the bolt is 14mm x 2.0mm (thread pitch 2.0mm).
