I thought I would help? and seem to upset you? Or so I don't understand anything ?
Once again I was told that KV-1 requires a special (it's own) size IR device and regular one (Tiger 1) won't fit without major filing

Some models even require their own special IR compatible mantlet, as part of the conversion. That's because mountings for he airsoft gun generally don't match those for recoil units.
Thus a conversion kit for a Tiger 1 from BB to IR/Recoil often includes all the bits needed- including revised mantlet, and is generally catered for.
I've not seen such a kit for the KV1/2. Yet, anyway.
Doubtless, modifications can be made- but the process will be fiddly. Another option might be, an IR configured turret:
Heng Long do an
entire turret with IR/Flash installed for the KV-1

This would help significantly, as it should fit your Taigen upper hull,

I think. Wiring differences should be minimal.
