umm.. in tucson there is one store called merles that might have it it is more of a parts store but they could. I don't know there address but it is on thornydale a little bit north of orange grove and south of ina. You could try calling some of the detail places and see if they know..but other then that I have no idea where to maybe get it without just buying online.
edit: I am on my laptop with the cellphone to get online so my connection is kind of slow or i would get the number for you but if you call merles they can probably tell you where you can get it if they don't have it.
