If you are looking for a Zenith voltage divider, look also at the Sylvania ECG replacement types - the Hi-Div series. An ECG Hi-DIV-3 replaces the 63-9896, 63-9897,63-9898, and the 63-9898-02. Various Mounting positions are possible with the ECG replacements too - unlike the Zenith OEMs.
The Internet archive has the ECG replacement guide from 1989, if you wish to look at the HI-DIV-3 data.
