I am doing new brakes all the way around on my 1989 CSX. So I am doing new bearings in the rear. I also want to put new wheel studs for the rear. I am have trouble with getting the right ones. I got 610-417 which are to small. They do not fit tight in the holes. I also tried 610-285 which are to big. I am hoping some one can help. Thanks for any help.
