Sheetmetal damage is common on a car of this age.
As already mentioned you can easily replace all of the damaged panels IF this really bothers you.
BUT what is MUCH more important to the long-term value and usefulness of the car is how straight the frame is and how well it drives. If the frame appears to be undamaged and it drives well, then don't worry too much about the sheetmetal repair.
I bought an old Jeep once that looked GREAT! After owning it for several weeks I discovered that the first foot or so of the frame had been replaced :shocked: , obviously due to an accident at one time (no wonder the grill & fenders looked "like new"...). Dispite this repair the Jeep always drove great and held up to whatever abuse I could deliver! I was the only one who ever knew about the repair, & I even had to point it out to the next owner when I went to sell it. He still has that Jeep & wouldn't part with it for all the money in China (which is a lot more money than it used to be!).
Just be happy that this isn't a repair on an Austin-Healey Sprite (I have several) or some similar unibody car. THAT would be a much greater concern as a similar rrepair would likely have negative impact on how a unibody car drives.
Remember, it IS a 36+ year old car!
At 36 I wasn't "like new" anymore either!
& I'm pretty certain that most of my cars will long outlive me!!
Don't worry too much about the small stuff!
Drive it & Enjoy it!!
"Cheers!"
