I'd bet it's exactly the same from 03 to 05. Call and ask Paxton, they are helpful usually. You can also call Doug Levin and he would know.
Thanks but I already have the Paxton installed, went with a 400lph pump and modded the basket and the 69# injectors. The external pullers and FMU paxton unit caused nothing but problems after a few years on it so I never planned to use it. Making a few minor changes to the the final tune this week and it should all be complete.I have a full paxton fuel setup that I just removed from my car, it would be pretty much plug and play for you. I have the Split Second box, two fuel pumps and the paxton fuel controller. Let me know if you're interested.
