Are all '95-'04 Body panels the same?

I am considering doing some body work on my flared '03.

Talking to the body guy, he has suggested just searching for a used bed and fender.

Are there specific differences that won't allow me to just take off my flares and mount them on an earlier or non-flared part?

 

I believe the 95-00 and 01-04 fenders are different, but the beds are the same. only thing different should be the tail lights.

 

Kind of was on the same track about the fenders, hard to tell from looking at pictures though.

I knew the tail lights are different, but, assume they mount exactly the same. Pretty sure the harness/wiring is different there too.

Thanks,
Peter

 

i think they are all the same

 

Wrong on the first part. Right on the second.

The only part of the body to change was the hood, which changed for 01 models to accommodate the raised grille.
