Bonanza is a trim level just like Silverado. They are Custom Deluxe, Scottsdale, Bonanza, Cheyenne, and finally Silverado. Bonanza gave you side moulding but no cab back moulding. The interior would have carpet and chrome trim on the door panels. It was a middle of the road trim package . They did use the same wheel covers as the Impalas . They do look a little funny on trucks . Of course you could order them with almost any option but I have had 3 or 4 Bonanzas and all have had a clock in the dash and tilt steering .My black 78 is a Bonanza and I just sold my 77 longbed Bonanza. It was Blue so I will try to find pics of it .
