OME Shock question

I'm in the middle of installing my Old Man Emu kit on my 00XJ and ran into a snag. Apparently I either lost or never got the front shock upper nuts. Anyone happen to know what size these things are? I thought I would be slick and just use the nuts from the stock shocks but they are different.

Call them, they should be able to send you some.
If you can, take one of the shocks with you to hardware store and pick up some?

Ummm . . . go to the hardware store buy like 5 different nuts and bring them home. It might cost you $2.
