fender extension threaded studs/nuts

Missing the studs/nuts for the fender extensions on my 72 Demon. They are what I believe to be 10-24 threaded studs that have a blank starter end on each end. Then there is the matching nuts which appear to be sheetmetal acorn type with threads. I am looking for about 6 of these. I know I can get my own threaded rod and nuts, but I prefer original stuff and these do not appear in any catalogs, so used is what I need.
