Hi CT Kid,
Yes, the resistances are not listed on the schematic for the 84, but they are listed on the 81, which is an older version of the 84, the big difference is that the 81 receives the "Police" band (180 meters?) Otherwise the resistance reading for the coils should be close. The big problem are the tickler coil for the Oscillator and the primaries for the antenna coil and the "IF coil" that feeds the 2nd detector. There are several articles on rewinding these primaries. Not horribly difficult.

Best Regards,
