If you are talking about the shipping brackets for the 6-CD radios, Coastiejoe (a member here) used to have one or two that he would loan out with a small deposit. When he received the brackets back, he would return your deposit. I don't know if he does that anymore, or even if he has anymore brackets, but you can ask him.
By all means, do not ship those 6-CD radios without the shipping bracket or the CD changer mechanism will fall off the tracks and will likely require that you send the radio to a repair shop to fix it. You also need to Park the mechanism before you diconnect power and remove it from your dash, and do not turn it upside-down until the bshipping racket is installed.
