Anybody know how high the rockers are welded into door jamb on 1967-1972 Chevy

I purchased some new sheet metal for both sides of my 1968 Chevy C10 which includes rockers, inner rockers then front and rear cab supports.

When I get to the rockers what does the factory installation of a rocker panel look like on a 1968 Chevy C10. I am not exactly sure if my factory rockers have been messed with already and want to see other examples of the door jamb area where the top of the rockers are.
