I don't know much about your car but...I have a 10" blade in the back of my Cherokee. Does your replica fit the standard (I think there are 2 or 3) style of insert? I bought mine at AutoZone but I saw it at WalMart as well. I think they carry sizes down to 9". Otherwise, maybe you can try jcwhitney.com.
Sorry I can't be of more help
