I'm from Aizawl, Mizoram, spending a few days in Delhi. My son called me from home saying that he needs the front brake drum for his Yamaha Ray Z scooter. The agent in Aizawl doesn't have the part and it seems that they have a reputation of having a lackadaisical attitude when it comes to providing their customers' needs, often keeping them waiting for months for spare parts.

The urgency part comes in because I have only one more day in Delhi, that is, June 20 (Friday). I'll really appreciate it if anyone could point me to a place where I can get the part.

I don't know Delhi very well, so please be as specific as possible. At present, I'm staying at Mizoram House in Vasant Vihar.
