It could be that the shut-off valves have mineral build up after 41 years. You may have to disassemble them to clean out the seats and replace the washers. (I’m assuming these are washer type faucets)
Are you sure there isn’t a restrictor in the shower head? That would be the easy fix if that’s the case.
Good Luck!
