Ive wrenched on defenders a lot - if you are going to be wallet holder for this project in Pakistan, might as well find some "satta broker" and burn your money there.
All mechanics / denter painter will say - Jee sirr kaam hojayga, bilkul inglish wala - while infact they wont know the first ABC of it.
just try asking how to set the tappets on a modern 300 tdi engine - or if they know how to time its injection pump. Or ask them what oil goes in the manual gear box. If you are looking at an old model - reworking the swivel ball axles can be a very expensive mistake if you are not aware of the "one shot" slumping grease that goes in there. They were originally filed with EP90 gear oil which leaks like crazy if the ball surfaces are not smooth.
They cannot even get an old land cruiser swivel set correctly.
