I found this forum link a couple weeks ago to see if anyone had a solution to this issue. I'm glad I did because I ordered a handful of these KAP bolt kit things for the guys to put on some trucks in the shop. Real slick. I see about 5-7 GM trucks a month come in with the broken bolts, but not too often is the gasket actually an issue. however, i am sure that can be replaced fairly easily too. I don't think they cost much either. all in all, it is a money and time saver. I dont know, but I'm not going to back to drilling them damn bolts out if I dont have to. Thanks for sharing everyone.
