I had to drill out all the lca bolts cuz rust ownz me. I was just wondering what size nut will fit the oem bolt for these cuz I had to cut the nut that was welded on the back side of it, and will I have to use lock washers? thanks

 

I think it's a 1.25 pitch, but to be safe, take the bolt to a hardware store and they should be able to help you out.
