I've made a couple of dashes, start with the metal that is in the stock dash, that way it will bolt in easyer. Use wood connected to the metal to get your basic shape, then glass your shape from there, Your design is going to be hard to cover without seams.I have a lot of pics of the dash I made for my transAm Roadster, it's about 90% complete. I don't know how this site is about pics here's a couple,I do have pics of every step if you want.There is going to be a carbonfiber insert with the grills blacked out .
