Its the one with the yellow arrow pointed to it.

I bought mine used and it was missing this bolt!

Anyone know what size it is so I don't have to guess? Thanks!!

 

Sorry, can't help you with the bolt size but how the heck did you get that picture???

Isn't the bolt in the same place on the other side of the car, the same thing? Can you just look at that one and get the size?

 

Notice the lift arms...

 

I got it from this website! they have an awesome high res pic of the undercarriage.
