sway bar bolt diamater

Anyone know the diamater of the front sway bar bolt? I have to drill one out that's fused to the mount essentially. 1/2" seems to be the closest but I don't have anything to measure it with.

The first result when searching google for "tj sway bar bolt" calls out a M12-1.75.

I replaced some of mine a few years ago since I tied my bumper/winch plate into two of the existing weld nuts and that sounds right to me.

Parts list confirms size as M12x1.75.

Online factory service manuals and parts lists - http://www.jeep4x4center.com/knowledge-base/index.htm
If it doesn't work properly, look for the service manual link at the bottom of the page.

bolt size wasn't an issue to find lol. I was seeing if anyone had a measurement for the diamater of the threaded end or the hole diamater so I know what size to re drill it to.

The front swaybar mount bolts that go into the frame are 10mm.

The four bolts that hold the swaybar mounts to the rear axle are 12mm. The little sway bar gets the big bolts, the big sway bar gets the little bolts.

The hole is in a threaded weld nut. I would drill it with a 10mm ish size and then tap it back to working condition with 7/16-14. Common, easy to find, easy to tap.
