95 Yj threaded hole sizes
 

The threaded holes in my 95 Yj frame are quite rusted so it is hard to
tell if the bolt is wrong or if the rust is causing them to go in
tight.

The rear ones (under frame behind shackles) I have been told are
10mm. Is this right?

The front ones (top of frame, used to mount tow hooks) seem to be 1/2
coarse thread but the previous owner installed a bumper with what
seems to be 12mm 1.75 thread bolt. The threads looked damaged when I
took them out. Anyone know the correct size?

Thanks

AFIK, none of the frame bolts on a YJ are metric, all SAE.. Front tow
hooks should be 1/2" SAE coarse, rear should be 3/8 SAE coarse.

By looking at some installation instructions on .pdf files for rear
bumpers and hitches from two different manufacturers, it is actually
7/16 in the rear. 1/2 in the front seems to be correct.

Thanks for the input.

Re: 95 Yj threaded hole sizes
 

My rear bolt holes have been drilled out to accept 6" long x1/2" through
bolts to hold the bumper and the rear tow hooks. It was the only way to
get enough strngth to feel comfortable with rear tow hooks.
