75 dart parting out. V8 disc brakes

I also have an original petty blue 73 duster. I am trying to decide if I should take the best of both these cars and build one, or if I should just sell both cars as a package deal? Both have clear titles. The duster only has rust in the lower quarters and doesn't even need trunk extensions!!! Floors are near perfect. The duster is a shell, and the dart runs and drives. Make me an offer on both cars and I'll go from there.
