Yes, Tabish you are absolutely right. Shahjee sells his franchise to Akber mechanical works and Raja mechanical works (thay are not original).
Original ShahJee was dead and his son name is AZAM (always wear Sindhi topi and white shalwar qamiz). He is a very good suspension specialist. Unfortunately, he closed his workshop from Gulshan-e-Iqbal block 7 and moved to another place.
If anybody has his contact information please share.
