Will a song cdx ca400 deck that i have laying around fit into my 2002 ford mustang with a spacer kit? deck dimensions are7 1/4 wide 2 1/8 high 6 3/8 depth? How hard is it to swap out this massive deck?

 

Why wouldnt it? it'd fit, it's normal deck dimensions...stick er in there...buy the kit though so it doesn't look like s%^& as for taking out the old system, I know that with my stang (91) you didn't need any special tools...but for those tools I am sure you can just use Coat hangers...then you'll probably need the adapter for the harness...ebay has all that stuff..
