Korina,
If all else fails, remove one of your studs and head down to your local NAPA store. They have a book you can go through with lots and lots and lots of studs. What your after is 2 7/32" long, size 12, either a 1.25 or 1.5 thread (check them since I can not remember which). I'm sure at least on will work in that book.
