Katzkin then Wet Okole. The Wet Okole would be the cheapest though, but are basically just good quality seat COVERS.
I have the Joshua Tree aluminum dash kit. Basically, it's just a "stick on" over your dash pieces. I haven't heard of a company that makes the "real deal" (i.e. a one-piece solid aluminum dash that replaces the whole unit.). If anyone knows of a company that offers this for sale... I'd like to know too!
