Damn another one. If I had a classic. I would do her up. With brand new components.
No no no You never touch a classic! Well maybe a sound system.. and turbo charger.. and mufflers.. and open air intake.. and suspensions.. you know nothing big...
Reason why as parts are extremely hard to come by. Therefore I would rather give her a new engine etc etc as close to the old one as possible. I would not modify the body or frame work. Maybe take out any back seats to enlarge the tank and the boot space.
