I cant get the new studs in, i have followed the write up to the letter. I had and old stud in the rear that stripped out when i was taking it off. I tried to replace it with the washer and the nut method and it wouldn't seat and it stripped out nut and stud in the process. I don't want strip out the new NISMO studs installing them in the front. The write up makes it sound easy, what the crap am i doing wrong?
