I think i was unclear/there has been a misinterpretation.
I was referring to the Mirage V's from Egypt, those have been upgraded to the Horus standard, which includes the RDY-3, the same radar present on Moroccan F-1s and a derivative of the M2K-5's RDY-2 (which the IAF operates).
In terms of the MMRCA bid, the IAF realistically will opt for Rafales, in terms of F-16s for PAF, new builds might be iffy, however, the Indians and Lockheed believe the F-21 is superior to the F-16 Block-72(which, it kind of is in some aspects however its effectively a rebadged F-16 to clear up its image in India after balakot- this can be kind of seen by 2 ways, LM saying its nicer than Block 52s which the Indians claimed to shoot down and its also superior to the supposed mainstay of the PAF) so the Americans could pull a whole Malaysia-Singapore thing where they arm both sides, just one side is favoured a little more. In terms of used F-16 though, there should be little to no objection from US in PAF picking up used low hour Euro airframes and then down the line slapping SLEP kits or even Upgrades at some point in the future.
In terms of Russian gear, i am firmly in the camp that they are not fit to fight in modern battlefields, atleast, in the air, Russia suffers from decades of underinvestment in its aviation sector. IMO any Russian gear without suitable modifications (primarily Chinese avionics/missiles) should not be considered, at all.
