Resistor Question

I’m rebuilding a circuit board nearly 30 years old .

The and resistors are 1K marked 1001.

Im assuming they are 5% tolorance .

They measure 0.958 on my meter while the others read 0.995.

Wondering if I should replace the resistors that are reading lower in value or if they are ok ?
 
It’s an EQ card for the Rockford Fosgate Symmertry .
Im checking everything on the eq card and the main board since the unit is old and when it was installed the unit didn’t really do much .

The factory Bose system in my truck sounded better then the new headunit , symmetry and new components and amps
