It's a 34 year old car.... I'm missing the part where you're saying it's in a "transitional phase". Because every single tiny thing on the car doesn't work...better watch out for mine then

I removed and boxed 5x the items you described on your car.
AND, people regularly want to buy it.
The car is old, unless its a concours car (which are for weenies not enthusiasts) every single thing isn't going to be perfect. Perfect has no soul...
Find the least expensive storage (free through a friend is ideal) you can and it will be like a savings account that actually grows.
3 years ago I almost sold mine bc motor went bad...VERY glad I didn't
