So i have a 08 ls 4 door that im trying to change from gray to black. The problem im having is all the part cars i find don't have black interiors.

So did 4 door cobalts come with black interiors?

 

Yes they did. All ss lnf sedan came with black interior. And there are ls and lt sedans with black interior. You can use a lot of the pieces from a coupe as well. I completely converted my sedan interior to all black.
