I have a 1989 Supra Comp with the same platform. I replaced my standard two black pads with custom SeaDek pad. I wanted a little extra coverage around the perimeter of the platform. SeaDek sent me a mylar plastic sheet to trace the platform on and note some basic dimensions to send back to them. They then sent me an approval drawing of what it was going to look like. I installed it myself and it was VERY easy. (You can check out installation videos on their website or on Youtube)
SeaDek had great customer service and great turn around time for my order. I would highly recommend that you check them out!
