There were a bunch of different part ##'s for the dividers.
IIRC none of the ones in the solid states crossed to the 800-860.
The 800-860 was used in hybrids. The only difference was
the HV was 30 KV on the SS sets & 25 KV on hybrids, again IIRC !
Someone must have an old Zenith parts book to look it up.
Also be sure ALL the 22-5001 caps are orange. They eat up the dividers
first then the CRT socket. Each one that opens gives you +2 KV
of HV, there are 5 of them IIRC.
Sorry for the IIRC's but its been YEARS & I was on the bench so
didnt have the pleasure of doing may flat chassii !
