I was having a little trouble extracting that @#%^&*!! bolt in the differential of a 10 bolt that I'm using for the Camaro(you know the bolt I'm talking about) , I also wanted to get the axle tubes welded up to the differential housing. I made a clasic mistake by telling "Take your time , I'm in no hurry for it." They stil knocked it out quickly and for a fair price to boot. I definitely will use their services again.
