By-election results to the Lok Sabha

Does anyone know where to find old results for Lok Sabha by-elections? I can only find results for general elections. (I'm looking for results to the 1974 Bombay South-Central by-election for a paper I'm writing).

Not sure if anyone cares, but I found the results to this.

Bombay Central By-election January 13, 1974
Roza Deshpande (CPI) 34.6%
V.R. Pandit (JS) 31.7%
Ramrao Adik (INC) 29.8%
Vikram Sawarkar (HS) 2.9%
(plus two independents with negligible votes)
Valid Votes = 235,699 (36.3% turnout)
CPI gain from INC
Adik was supported by the Sena and some RPI factions (Ambedkarites).

This took place amidst a mass textile strike and a boycott of the vote by the Dalit Panthers. The boycott appears to have been successful in stopping Dalits from voting for the RPI backed candidate. This was the third by-election loss in a row by the INC and the election kickstarted the Worli riots, which pitted the Panthers against the police and the Sena.
