What mirrors did my truck have originally? 1983

[stomper]

I assumed the big mirrors were original but now I'm not so sure it didn't have the little default sport mirrors. What makes me think that is no mirror called out on the SPID and the rivets in the area where sport mirrors mount. Although the rivets pattern isn't where I'd expect sport mirror mount holes to me. 3 reverse pattern holes? Also, this truck was outfitted with a number of heavy towing features when I got it. i.e 5th wheel hitch, gooseneck ball mount in bed, spark retard unit, trailer brake controller, and in bed fuel tank.
