Does anyone know if an 07 tailgate with a spoiler will fit on an 04?

 

It should, since its just about the only thing that didnt change from 03 to 08.....with perhaps the exception of anything that's bolted on to the tailgate.

 

only thing that didnt change? only thing that changed was the hemi got MDS, it got a new front end...4x4 got different suspension and a different interior....exterior wise...from the winshield back is the same except for the 07 & 08 tail lights

 

It should fit.
You can buy the spoiler for around $60 bucks. If you buy the kit it comes with screws and thread setters. It's not hard to install. I installed mine, it just took me a while because I double checked where to drill holes like a hundred times. Everything turned out perfect.

 

they will interchange......
