All my recommendations on pw are sourced from when I lived in Karachi, Pakistan.
E.g. battery terminals. I can guide you where to buy genuine HD truck items, advance level greases, speciality sealants, speciality tools, speciality instrumentation.. for engines, machinery, hydraulics, pneumatics etc etc.
All are sold in or near old karachi.
Your problem is classic Pakistani approach.
You want spare parts available from local cigarette shop and any heroin addict on the roadside should be able to install for rs 100..
LOL.. i feel sad for you, but you gained nothing from this platform, infact you are behaving like a parasite, you only recieve help but never offer anything.
