8 3/4 wheel stud part #

I dont even know if this is even the right place to post this but here goes. Ok so on my 72 dart with a 8 3/4 rear big lug I had to cut off one wheel stud, one stud broken, and 1 stud stripped I am in the middle of replacing all 5. Well I had 2 good studs and one good lug nut to take to the parts store to see if they had one that matched but I was met with some lady being a big ol b#$%!. she was like im not gonna spend all day looking at wheel studs unless you have a part number so I told her ill take my business to someone who wants my money not only that but I could tell she knew nothing about her job except punching in part numbers. So here I am if any knows a good place to order these studs or has a part number I would greatly appreciate it.
