Just did the scarebird disc change on my 65 dart. Scarebird recommends changing to longer studs (Dorman #610-156). Problem is the knurl on the stud is too skinny for my hub. So I bought new studs with a slightly bigger knurl (Dorman #610-114). New studs were tight untill driving around started to feel some wobble. Don't know how it's coming undone because I grinded the caliper to where it doesn't rub on my rim anymore.
