How stable do they need to be in an old radio where components values

That depends partly on the circuit design and partly on how much any
other components in that circuit may have drifted. Without that
information, the question can not be answered.

The question is pretty much answered by the fact that most antique
radios used 20% carbon resistors. Many of these original resistors
have aged upwards of 100% over time, and the radios often still
run "just fine". The manufacturers saw no need to use high tolorence
components, and most of the circuits are self biasing and self
compensating to some degree.

Vintage radios aren't rocket science. Good NOS carbon
comps from reputable manufacturers are fine.
