Where can I find a replacement? Apparently once upon a time, before I got this car, somebody used a regular threaded nut on the very front stud. Over time, I assume corrosion seized the nut to the stud. When I trying to loosen the nut, the entire stud came out of the scoop. So I need a replacement stud and I assume I'll have to epoxy it into the scoop since the threads in the scoop are now stripped. What size are the threads on the original studs?
