Yup, it's a 32mm, I picked up a crapsman one for about $6. Jeff is right tho, gettin the arm off of the splines is a real pain. Get yourself a decent pittman arm puller i.e. NOT harbor freight, I broke one of those in half and the half that came off almost took my head out <img src="/forums/images/graemlins/scared.gif" alt="" /> I got one from auto bone and it worked for me. Soak the splines in PB blaster or your favorite brand of penetrating oil a couple of days in advance, then use a good long beaker bar, mine's a 18 incher and it came off super easy, well, once I got the right puller that is <img src="/forums/images/graemlins/lol.gif" alt="" />

Good Luck!
