I have been fitting my sketch to the rocker and have some minor tweaks. Ill post in a few.
Final fit.
The only thing that I am thinking is the 7" radius should be more like 8" or maybe 9", 10 is way too flat, but with the trim on I have to estimate based on the outer surface if the trim.
The inside of the rocker is shaped something like this but my car is a factory undercoat car so the dimensions are almost impossible to determine
