1966 C10 Fleetside Body plug list?

[msg]

I am putting together an order and I think there are more than 4 body plugs that I need. So far I have the rocker panel plugs and the lower door plugs that are on the side of the door below the door latch. I must be missing a few cause I went through a box of "extra" parts I didnt label as I disassembled and I cant recall where this one came from. Its around 2 inches wide. Is there a list someone may have to show what I should order just in case Im missing a crucial one?
