First, welcome to the Forum !
To answer your questions, consensus is not really needed on these, just facts. If Wide Ovals were ordered, they "{automatically came with 6" steel wheels ; unless the Styled Steel Wheels were also ordered, in which case you got 5-1/2" wheels (4-1/2" wide wheels were Standard for 6 cylinder cars, and 5.00" for V8's).
As for Wheel Covers, the 9-5/8" or 10-1/2" hub caps were Standard on Coupes and Convertibles, and on the Fastbacks, the full Wheel Cover was Standard (see attached). This full Wheel Cover (as well as several other Full Wheel Covers) was Optional on Coupes and Convertibles.
Hope this helps.
