I have a 2006 Mazda 3 Sport 2.3. DS front control arm rear bushing came apart, was going to just change the arm because it was only $50 more than the bushing kit. During removal I had the front bolt head break off because it was seized in the bushing. I'm just wondering what thread pitch it is so I can find one before I cut the control arm off around the bolt and make the car immobile.
