First, it shows some "conscience" that you ask the question, and that's good. If ANY car, even in bad shape, but with solid "bones" is rare, like A10, etc in the case of a 69 Bee, it demands restoration.
Having said that, I have a 70 V-code Track Pak Roadrunner, post car, 4 speed. It looked good enough when I bought it to win a Top 50 trophy at Mopars at the Battleship, basically just like I got it, and I have won Top 50 ever since, but I know it will never be Best of Show. I have 2 friends with Best of Show 70 Roadrunners, and my kind of fun doesn't equate to that route, although I respect and admire their cars, I would go nuts trying to do a car like theirs. It has a 71 440 with aluminum 6 bbl intake, and Dana 60 w/3.54s.
When I test drove it, it pulled right which got worse on braking. The trunk pan has some rust, that was painted over

and a couple of other issues.
I decided to focus on safety, preservation, improvement, and since it didn't have a numbers matching motor, I felt like that was my "pass" to do what I want to it. So disc brake conversion in the front was #1, replaced the lower control arm that was bent #2, and so on.
I have a Passon 5 speed for it going in in the next couple of weeks before Crusin' the Coast. I get to enjoy it crusing, at car shows, on the track, and plan on a Street Lynx rear suspension, replacing the bench seat with custom buckets, etc. I will put a stroker in it in the future, but it MUST use the 6 bbl setup, and I already have a N96 hood and some of the associated parts for that.
I will enjoy it by appreciating what I have guilt free because of the non-numbers matching motor, but I will "honor" its heritage by keeping the carb/intake setup-although I may do a 6bbl throttle body one day that uses the factory air cleaner.
Long story, but I hope that you get something from that perspective. I don't anticipate ever replacing it and I'm 55, so I want to do what makes ME happy. It is MY car after all. If it would have been numbers matching and I could have afforded to buy it, I would have kept it "day 2" stock with bolt-ons that could be removed to return it to factory original, or pulled the motor and archived it so I could beat on it without fear.
