Having done this ages ago with Osama, with same tool and my extra hands but on a different car
Unfortunately I am in Karachi now and don't know a single soul who would be able to do this process. Hope someone in Karachi can point out someone who does this job even if it means I have to help them with it!
And it's not only about explaining to the so called ustaad it also means one needs to have that tool to make this happen not just a plier to take the valve seal off.
