I came a across a mechanic shop that has a business specializing in exhaust manifolds and the consistent problem that GM has with broken bolts. He has engineered some repair parts that you can use to fix it without having to take out the broken bolts.. pretty cool. I noticed that someone else has posted something on this forum about it too a while back, I'm glad that word is getting out about it. I used the parts on my Silverado, but I know they fit all different types and sizes of vehicles. Check em' out.. Home - Kral Auto Parts
