equipment of planes in Arab-Israeli wars and Falkland war

Are there any sources which could help me with these questions:

Did Egyptian, Syrian and Argentinean planes have (and if yes, in what numbers? how many of the air force fleet, percentage wise, had them?) basic/crude RWR systems?
Did they have RWR system providing the pilots with information of incoming missile’s bearing?
Did they have flares?
Did they have chaff?

All four of those questions would need to be answered for 4 different wars:
1967. six day war
1973. yom kippur war
1982. lebanon war
1982. falklands war

So far I’ve managed to find answer just for chaff question for Falklands war. Argentineans did not have chaff, which surprised me. Only at the end of war a limited number of planes had very improvised chaff dispensers. So if in 1982. we had that, is it equally possible that 10 or more years earlier bunch of mig19s, mig21s, su7s etc did not have those important systems?
