318 Duster Rebuild - pros and cons of keeping matching numbers

Hi Steve - Good to hear from you. I’ve decided to stay with the car for the long run - my Son has expressed interest in having it eventually. I wimped out and took the car to a restoration shop that has a great reputation for beautiful cars and slow turnaround. I’m waiting to get contact info for a shop that just rebuilt a Barracuda engine for him. I’ve been advised to insist on an engine rebuild by someone that specializes in Mopar engines. I don’t expect to see my car for a long time - but I’m hoping that it will look and run a lot like it did when I drove it off the Chrysler lot in 1971. I’ve even purchased seat covers that are made from the original material. The car is currently being disassembled and stripped down to bare metal. After that - I’ll get the good or bad news about how much metal needs to be replaced. I already know that the firewall will be replaced. I’m also having AC and power steering added to the car. Engine and transmission will be rebuilt as deemed necessary.
Good to know it's staying in the family. I'm sure it's going to look great when it's all done and be worth the wait. Keep us up to date on the progress. I'm sure many people here have interest in what's happening with a one owner car. Best of luck with it and take care.
