I started by making a mold of a Cayman dash and then grafted it to the remains of the metal 928 dash frame. The door panels are more time consuming. The doors are at least a foot longer than the 987 door panels that I used as donors. Some day I will get around to finishing it. I am just about to get the car running again. Once I do that, maybe I will be more motivated to finish the interior work. If you have any specific questions let me know how I can help...
