That car cannot be fixed. You need to ship it up here to me
I would adjust both/ all 4 drum brakes up tight, bleed the brakes, and see what that gets, then slack off the adjusters until they rub "lightly" and go from there.
If you are unfamiliar with drum brakes they can be quite deceiving, as simple as they are, AKA if the drums are worn or been "turned" and the shoes new, the shoes will effectively be too small for the now larger drums. Back in the day, you had the shoes "arced" which is a precision grinder that grinds off lining so that the shoes then match the drum diameter.
