Need quick help on bolt size (auto trans skid plate)

I'm installing a set of LoD sliders on my JK and it uses the stock transmission skid plate bolt where it attaches on the bottom of the frame. I believe it is something like a 7/16. I have a manual transmission, so no stock bolt. Can someone tell me exactly what bolt size/thread it is?? My frame has the nut inside (I assume welded in every frame), so I need the exact bolt size.

Thanks! I tried that and it didn't quite fit. Then I realized all I had to do was pull a bolt from the gas tank skid plate. You were close, but the pitch is 1.5 and not 1.75. After a big search, I found some at a hardware store.

I'll post pictures once I get them on. Thanks again!

The JK's skid bolts are M12 x 1.5, a PITA to find. There are very limited head types in that size as well. I've looked everywhere for a set of button heads and have had no luck whatsoever. Poly suggests drilling the holes out and tapping at 1/2 x 20, may be my next move.
