how much for a 70 dart?

a number 5 "restorable needing complete restoration) 1970 340 swinger is valued at $2,400 in the old car price guide. a number 4 car which is"driveable needing minor work to be complete, from 20 feet away there is no doubt it needs a lot of help" is valued at $4,000. it's the only info i have.
