I am at work now and want to order online a longer carb stud and wing nut. Truck has 360 with edlebrock 4 barrel carb and aftermarket air cleaner. I'm putting back the factory air cleaner and need longer stud. Is there a standard size? I can't tell the size by looking, am stuck at work and don't have much time off lately and really want to order it now. Is this right for an edlebrock carb "1/4-20"? I figure they all must be the same.

Thank. Anxious to get it ordered and don't feel like dealing auto parts stores even if I get the time to get there in next few days.
