I am trying to swap out the Fuel Tank Selector Valve on my 85 Silverado and I cannot seem to get the size of the bolt heads. They are in an unbelievably hard to get to place between the frame and the cab (Thanks GM!!), It seems to be larger than a 7/16 inch but smaller than a half inch. Any ideas on the size and how to get these things out?? Any assistance is appreciated.
