You might try connecting a silver mica cap of about 100-220 pF or so across trimmer 20. This will decrease the tuning range of the BC oscillator and give a bit more adjustment.
Trimmer 20 is the padding cap for the BC band osc and should be adjusted at 580 kHz for proper tracking with the ant stage and accurate dial calibration at the low end of the dial.
