Cudaspaz - the brackets were from Corbeau and designed specifically for 67-76 (I beleive) A body mopars. I will try to get some pics up of them. Along with those brackets I made some of my own using squared 2x2 inch steel tubing to basically add some seat height. I prefer a local sale, no shipping or anything but if that doesn't work out I will sell all of the brackets for 100 bucks.
As of now I will bump this thread and drop the price for EVERYTHING, seats brackets and 5 point belt to 350.00.
