Hello Britishguy,
What I can say , you don't need to do all the exams to get a MALAYSIAN CONVERSION with a FAA license .
You will only need to do an airlaw exam but that's not a problem . Then a flight test but this is what the company arranges for you .
Don''t think you need to do all the exams unless you want a full conversion and wants the Malaysian License . But you can fly 737's and enjoy the Malaysian skies with just a conversion . You can always study while you already flying if you need /want the full Mal. licence.
Believe me that's what I had to do , only airlaw ! Go for it cause it's great in Malaysia , you will enjoy it !
I will try to see if I can get the contact person of their CAD who deals with conversions/licnese etc ......
