I wonder! Who, even if the so-professed 'Sanatani Sikh', would ask these questions? If you are serious about getting the information, why don't you yourself check on internet? However, that does not matter.
As per reports 131 Gurudwaras and 11 Sikh educational institutions suffered some damage during the 1984 riots and were repaired later.
Among the Sikh Gurudwaras in South India, these two are the most famous. Gurudwara Jhira Sahib in Bidar, Karnataka, a place which Sri Guru Nanak ji visited, and Gurudwara Sachkhand Sahib in Nanded, Maharashtra, where Sri Guru Gobind Singh ji breathed his last.
Sri Guru Nanak Sahib ji was born in Nankana Sahib, which is now in Pakistan.
