Can you name this part???

sorry for the late reply, no I didn't find any and the cost to get them made was crazy. I'll keep looking and keep you in mind. There's a guy on kijiji/ontario that is selling a gts in black, i talked to him and he said that he's got a complete convertible roof for sale but wasn't sure if the retainer was good. I think the ad is still there, I'm 6 hours away from him
