Looking for a driver

I accepted the offer for my 72 matching number 340 4 speed Duster today and now I'm looking for a 70-71 340 Duster that can be registered,insured and be driven as I fix things. I got sad on the phone as I was makung the buyer a happy guy.
I only had the car a little over a year but did a lot of work and learned a few things along the way.At this stage of my life I think an automatic will work but of course I would rather have a stick. What do you think is a realistic dollar amount I could expect to pay.....The car has to be a real H code car and matching drive train would be great. Pm with information.
