Wheel stud, no one has it, need my truck!

[bradkline7.3]

I had a squeek in the front end and a vibration so I pull the front right tire check it out, and as I am finger tightening the lug nut back on the wheel stud breaks off. It is a 1997 F350 CC LB DRW 7.3 4x4. BUUUT, it was a dually conversion. I took the stud around to parts stores and a Ford dealership and they all say they don't have one this big! They all tried giving me what their books show for this part and it is a much longer, skinnier wheel stud. The one I have says A-4 on the top with a logo that looks like a sun, and it says R on the tip of it. Is there anyway for me to find out what the front end is, or where to find this wheel stud? Ebay doesn't have any that look similar.

Can't drive the truck until I replace this one (will probably replace all of them since this one snapped off so easy. Any help is appreciated.
