anyway...i believe they were 14mm? possibly 12mm. thread pitch? IDK. You'd be better off pulling a bolt like I did, going to the hardware store and getting a longer one, a spacer nut, and a new nut. The tabs I used are the same dimentions as the ones Wayne @ Underdog sells...2" x 6". If you made the brackets longer, there'd be no need for the spacer nut. We used what we had w/o having gas...i originally made nice and tight fitting tabs, BUT 06+ trucks use bumper covers and doesn't use the existing bolts like 05 and older trucks use to mount their tabs..
