Hey guys. New member here. So I’m doing an entire drivetrain swap from an 05 EXT LT to an 03 EXT LS. I’ve already pulled the drivetrain from the 05. And as I’m pulling the set out of the 03 I’m noticing some key differences like the fuel system having an extra port on the fuel rail of 03. Is this as easy as just swapping the fuel rail from the 03 to the 05 when installing the 05? Also the valve cover is plastic on the 03 but metal on the 05. Which also means the coils are different but share the same plug. Should I swap over the valve cover also? Any insight would be appreciated. Thanks in advance guys!
