The resistor in the detector/AVC circuit is not critical so you can use anything close. Remember the original resistors had a 20% tolerance, so anything from 40K to 60K should be fine.

Is the volume control in your radio original? If it is I would be surprised as they usually go high in value. The one in my 89 reads about 800K but still works fine. If you are concerned about the value, you can add a 100K in series with the high side of the present control to apply the correct load to the detector. This radio has plenty of audio gain so you will not notice the slight loss from the voltage divider created.
