This worked perfectly in my situation. Broken bolt on exhaust manifold, rear on passenger side, Cyl. 8, 2016 Chevy Express Van with 6.0. Bolted bracket onto head with 2 supplied bolts, 3rd bolt goes through threaded hole and pushes against exhaust manifold. Slowly tightened until gap reduced enough to seal exhaust leak. No more burnt plug wires. 👍 Will also fit Cyl 1 on front drivers side.
When a bolt broke on my 5.3 and was impossible to remove with the heads on, I searched for a solution.
Found it with this Dorman bracket!
Highly recommend!
