I have broke off several of my 1/2 studs and decided to go 5/8 if I am going to replace the broken ones. So I get the kit in, no instructions or anything. Anyways, do you drill the hole in the flange big enough to slide the stud in, then run the nut on the back to hold it in, or do you drill the hole smaller and thread it? If you are supposed to thread it, what is the thread pitch? Also, if it is supposed to be threaded, where did you find a tap big enough, and did you have to buy a set it came in, or get it idividually? I am thinking it would be stronger if it was threaded in and may go that way reguardless, but I would like to hear from somebody who has put them in.
