Does anyone know what size the Injector Bracket Studs and nuts are? Were could one be found locally?

I broke one today and need to replace. There is part of it still coming out of the intake. Any sugestions on how to get it out? I was thinking about trying some vise-grips.

Thanks for your help.

Vice grips should work.I doubt the nut or stud could be found locally.I got some from Kdeal.Stainless.
