where do I find them online. I want to replace all my interior with black panels (plastic) instead of the old original ugly tan stuff.

 

Why not paint your old panels?

Krylon Fusion does wonders on interior parts.

 

Idk, just rather have new ones so it wont look as ghetto as the outside does lol.

 

nah....that krylon fusion, if prepped right doesn't look too bad at all

 

And what is the proper way of doing so?

 

you have 3 options. find a wrecked fx4 level 2 and pull the factory black panels. dye them. or get them wrapped in material. they all have the advantages and disadvantages. finding a level 2 will probably take some time and cost some money. if you dye them, you take the risk of it scratching, flaking off, or fading over time. advantage is it's the cheapest way. wrapping the panels is time consuming, but it looks really nice and you don't have to worry about scratching or flaking. if you don't know how to work with vinyl, then it can get expensive though.
