Have you checked with the Kabariayas on Lawrance Road and Shershah. I have always found a few winches there.
Where will you get an electric winch on Pakwheel. Only possibility is that we invite OOdh Bhai with Jeep on G2G ouur un ke jeep see brand new winch chappar kar lete hain.
Btw electrical winches in various conditions are avialable in the above mentioned place starting from 12k to 30k.
