Scrambler 500

So I just picked up a 2009 scrambler 500 4×4 and didn’t know finding aftermarket parts for it would be such a nightmare. I’d like to find different color bodywork-mines red and white and I’d like to make it blue and black. I’d also like to get aluminum wheels to lighten it up a bit, but I want somewhat strong aluminum wheels since I’ll most be doing trail riding. I’d also like to widen it up with more offset in the wheels.
Also, does anyone know if trail blazers, sport 400, scrambler 400 have a lot of interchangeable parts such as bodywork?
So if you know much about wheels and where to buy bodywork please let me know! Thanks!
