Hi Guys. I'm looking to buy a motor for my 2005 Grand Prix GT 3.8L v6 VIN 2. I've called local salvage yards and they tell me that a 2006 is not a listing for a replacement engine, and I can not understand why this is? Is there some things you have to change on the 2006 engine to make it compatable in my 2005 car. I'll also include a search engine for engines I found online and if u use the vin2 option for a 2005 then a 2006 they come up with different listings as well......any advice would be greatly appreciated as the 2006 motor i found has the lowest mileage.
