goodmark rear quarter skins for 67 cuda.

I am in the same situation with rear quarters. I have the Goodmarks and just hate to use them if AMD is coming out with some. Wondering if anyone has took the chance at the cost for the fast back ones from AMD. I would do it if they were sharp lines and better than the skins I have. Hate to blow a bunch of cash on more sheet metal just to cut them down. Filler is cheap but like others share hate to use to much.
