Maximal Performance Camber/Toe Lock Nut Size

[3000GTPro]

Does anyone with a maximal performance camber/toe kit know what size crescent wrench I need to loosen the nuts that lock the adjusting arms in place?

ask Maximal (http://www.3sgto.org/members/maximal.html) himself

I did. He wasn't sure at first, so I asked on here. He says he's 95% sure the size is 1 1/8 inches or 29 mm. Can anyone confirm this for me?
