I am running an 03 bed on my 02 and it matches perfect. If love to trade because mine is black and all but I'm in Texas haha

 

Body lines match, wiring may be different, but then again stepsides are a different animal all together

 

The only wiring difference I had was the distribution block for the harness was mounted on the bed instead of the frame or vice versa

 

Simman- I'd trade ya in a heartbeat if you're ever up here near Ohio lol, but now that I know the 99-02 will fit I'd consider one of those too, I think the distribution block is on the frame on my 04. As far as I can gather the main thing about going from stepside to fleetside is changing the bed, bumper, gas tank filler neck, and possibly some minor wiring changes but it's pretty straight forward
