How much difference is there between a box from a '02 Screw and '04 Screw? My friend has one laying around from his old truck and I was just wondering if it'd fit in my '04.

 

I don't think it will. If you check supercrewsound it looks like the center hump cut out is larger (higher) on the 04-06. And it also looks like the hinge cut out is on the opposite end of the box. May be some other issues, but this is all I can see from the pics.
