The early kick panels also screw onto the door jamb in a different position too. The repro panels are the later position.
I don't know whether this coincides with the 1 and 2 piece design, but the repops are incorrect for early 69s.
If they were smart, they'd produce these with 2 tabs, and the customer simply cuts off or trims the one he doesn't need.
Instead, I have to try and plastic weld these where I need them.
My 69 is an 11C build.
