Cool truck, congrats. Bonanzas are cool. Don't see many shortbeds. The predecessor to the Bonanza was the 72-only Highlander package. Used the same YG6-8 RPO codes for various option package groups. Regarding the mention of the light blue Bonanza above - if it was a 76 by chance, it's possible it was also a Spirit of 76 truck. Neat little oddball that I've always liked a lot. Congrats on a neat buy - that seat is original, there were 4 variations of that vinyl seat cover. Vinyl sucks, but cool patterns. I don't know anyone that repops it though
