i want to remove my old stock cd playerin my 99 mustang cause i got a new headunit and that replaced my tape palyer unit.. so my question is ..are there any covers that i can get to cover the hole that would be there if i did remove my cd player.. or what should i put in there?

 

They make akit (Metra, Scosche) that has a pocket under the head unit. I think the same one will work if ts a single din or din and a half. You'll need the wiring harness with this also. IIRC, there maybe 2 screws under the radio and then the trim bezel pops out. You'll need the pull pins to pull the factory radio out. Hope this might help you bro.
