replacement studs for ichiba wheel spacers v2
 

hi folks, anybody know what kind of studs the ichiba v2 wheel spacers use? tire shop damaged a couple nuts and i ended up with a broken stud on two spacers. the thread is the same as the stock stud, but at least the knurl is a different width. not sure how to approach getting a like for like replacement. i have 20mm in the front and 25mm in the back. both studs appear to be the same length. thanks in advance
