Review on πŸš— Dorman 03412B Exhaust Manifold Hardware Kit - Complete Solution for Reliable Exhaust System Performance by Rubeen Black

Revainrating 2 out of 5

Installation instructions are wrong!

Will not fit Chevy Express 5.7 or Vortec 5.3 or 5.7 between 1996 and 2003 These screws are too long. They are mislisted at all parts stores, not just Amazon. If you have a 350 Vortec with a cast iron header. These screws don't fit.

Pros
  • Great for me
Cons
  • Repair
