Having problems with your Cars & Trucks ?
In a Pontiac 2002 vs. 1999 grand prix gt 3.8 liter, is the rear exhaust manifold the same style on both engines or are they different?
An interchange manual could tell you. Call a salvage yard and ask them. Those interchange manuals are quite expensive to buy and keep updated. Salvage yards require them to know if parts are interchangeable. They could quickly check for you.
