That is a hard find. Trying to get a metric thread into a 3/8's course hole is always a bich

Are you sure its a M10? My 97 parts book says the bolts on the top of the bell housing are M12x1.75x50

Not a chance. Wrong bolts altogether..

I've hung close to a dozen 4.0's and 4.2's of engine stands. Everything from 82-03. I've always used standard bolts. I'm supprised to hear you have metric in there.

I have no clue what's actually there. I was just going off the 97 parts book, Hex Head M12x1.75x50. But you know how these things go. My body tag says I drive an automatic. If thats true, its the most labor intensive auto I've ever driven. Lol. P.S. the 97 is the most hodge-podged Jeep in the TJ series. I don't doubt anything with mine anymore.

No worries. The top bolts are inverted torx 99% of the time, and a 12mm is basically a half inch bolt. Those are used on the bottom of the inspection plate for sure (the 18mm on both nut and bolt ones), and maybe somewhere on the side, but definately not on the top. Those ones are tiny in comparison to a 12mm.
