I'm not sure if it's been done yet, but here is a Carbon Fiber Gas Door. You do not have to re-size it when you add it, I've found this size to fit most of the cars, have not tried it on MRT, LX4 and LX6, I'm sure a little re-sizing will do perfectly, Again I was not sure if this has been added or not. I've been working on it for a while, finding the correct sizes and such Well hope you like the finished product.
