AAR rear spoiler for duster

Do you mean one like this? I have one more. I will see if my son wants to sell it. I think he was going to cut it down for his Omni. If he is willing to let it go I will post it. I have seen quite a few on Search Tempest in the past. Keep and eye out I seen them on Novas and other makes. I got one off of 70 Nova in a yard.
