I suggest removing these flaps and adding a modifcation for them (just like on the T-62M-1), which would reduce the grind for actually good mods and it would just make the T-64A look much better without them if you so choose to unequip that modification.
These also increase the frontal silouette of the tank making it easier to spot on long range engagements and they are nearly useless against HEAT shells so having a choice to unequip them would be nice.
