XT6 Spindle bolt size(possible camber adjustment)

[jmr052]

Pretty much says it all. The alignment shop has some special bolts to help w/ the positive camber that has occured after the 5-lug swap but I need to know the correct size to buy. Has anyone ever seen these bolts, or used them? They are a bit strange looking as the part in the middle is a small cam and that is what creates the adjustment.

 

Thanks,

Jay
