It just kinda depends on which parts your looking for to if they were used elsewhere. In general 2006-2008 (and 2009 2500/3500) trucks will work for most everything
Window switches are gonna be 2006-2008. 2002-2005s might work too but I wouldn’t chance it
Fog lights should work from 2002-2008 trucks. I just bought a jumper harness off of amazon for my 2006 and it worked great
Seats from any truck between 2002 and 2018 will bolt up and have the power movement wired in without too much issue. Also 2019-present classics and the 2019-present 2500 and 3500s will work just as well. But if you don’t like a little custom wiring you’d have to find 2006-2008 seats
The instrument cluster is strictly 2006. I’m not sure what all is different besides the backlighting, but if your cluster goes out replace it with an ‘06 truck only. To be safe I would only replace all electrical modules with 2006 truck modules. Sometimes things can get wonky if other things are thrown in
Radio, shoot honestly these radios are everywhere. Dodge avengers, PT cruisers, durangoes, sebrings, etc from 2004 until about 2010. Basically if it has the same shape as your radio it’ll work. Just make sure any OEM radio you buy has the options you want. They have a 3 letter code right below the right turn knob. (aux port (REF), 6-disk (RAQ), etc)
The taillights were used from 2002-2006. Headlights went from 2006-2008, however 2006s came with an amber bar at the bottom of the headlight. I didn’t like it so I bought some 2007-2008 style headlights and got rid of it
Exterior wise, doors, bed, cab, rear bumper, tailgate and hood are all interchangeable between 2002-2008. Quarter panels, grille, and front bumper are 2006-2008 only
There is more but honestly theres too many small parts to list. Some PT cruisers and jeep liberty’s use the same door lock push knob, some chrysler sebrings use the same cruise control switches, and you can pull the little window switch outer covers off of older PT Cruisers and they’ll fit your switches, just to name a few. I’ve already wrote a book lol but in general 2006-2008 trucks will have everything you need, however SOME other chryslers jeeps and dodges will have a few components that will fit in your truck
