From its data sheet Pin 6 is the main oscillator connection and has 250mV RMS on it with respect to ground when the supply voltage is 4.5V.
If you make a capacitive divider from Pin 6 to GND and choose the upper cap in the divider to be only 1-2 pF and the lower cap in the divider would be the input cap value of your frequency meter and maybe some more you add to it, then maybe you can still get enough oscillator voltage at the divider output to drive the meter. Of course you have to compensate the frequency shift of the oscillator due to the extra caps but that is simple.
Make sure to substract (or add) 70kHz to the measured oscillator frequency due to the 70kHz IF used to get the exact reception frequency!
