OK, i am having the hardest time with this. You know when you take the stock radio out of a mustang and the cd player to put in an after market deck you have a space where the stock cd player was? Well, i'm trying to find the plastic pocket insert to put in that hole and for some reason i can't find it online ANYWHERE! I know this shouldn't be this hard. If anyone knows where i can find one of these could you PLEASE let me know, thanks!
