@msm sir geee u will get it from ur old spare parts dealers market,In rwp its called chah sultan,like in lhr bilalgunj i dont know wat is the market name in karachi,ask them for RPM METER OF SUZUKI SWIFT GTI for khyber,
any good electrition can fit it b/z it will be exactly the same size as normal khybers meter
i exactly dont know how much it cost last time i saw this in peshawer and they were demanding 6000rs for it but that was a year ago so u need to check that
