I just installed the Bullitt pedals - what a P.I.T.A.! When I reinstalled the gas pedal bracket to the studs coming through the firewall, the one stud on the top left is loose and turns and I can't tighten the nut on it. How can I fix that stud from moving? Any ideas would be greatly appreciated. Thanks!

the stock pedal and was able to install the bullitt one ok.
