I purchased a 1979 shortbed C10 Chevy truck to restore. The model is a Bonanza. That model never shows up on websites or in parts catalogs. It is a very stripped down model. I'm trying to figure out what other model it is the closest to. It has a 305 engine and a TH400 tranny. I'm changing the engine to a 350. There isn't much trim. The cab has no headliner. The seat is a bench style and is nothing special. The doors are padded halfway down. There is no AC and roll-up windows. Most of the time I don't really need the model but sometimes the site requires it. I normally choose Scottsdale but I'm not sure this is the closest to what I have. Can anyone help?
