Shain, I had a similar situation with the Pivot bolt on the standard transmission. I found no apparent damage and replaced it with the up grade and have had no trouble in the past 5 years. As for the TAB, that goes to show you and the group the standard 10.9 grade bolt isn't as bad as a lot of people let on to be after all, it takes the abuse and keeps on going. My 10.9 were bent and loose as I thought they would be but not broken so I replaced them with the 12.9 up grade and the rear end feels much tighter. I would defiantly check for any damage, but soft metal rubbing on soft metal may not have done as much as you thought. Just depends on time. John hervey http://www.specialtauto.com/bodyparts.shtml
