anyone from Karachi knows where magazine lane is, and they also know where all the afghan traders are in the building selling weird stuff - where this term "kabuli" was coined, the shops selling auction stuff too are there.
Those little shops also had the little push clips you see on the wiring harnesses of toyota where they are held to the body. - They can be bought there - if that is too much, Genuine Hino, Volvo and CAT terminals are sold too.
If that is too much (because you dont know anyone having a hydraulic crimper - unlike us Karachi people who would just take it to Lawrence rd) We had little shops in plaza that woud sell you lead cast terminals complete with 1/0 wire already attached to it - used a lot by generator repair people.
It seems like you are a burger type person who visits superficial shops only, not real business places.
The reason I write here - is for people to benefit from my own experience. Too bad its a blinded effort as you claim "yahan yehi milta hai"
even youngsters are far better than you in finding stuff man!
