Bizio,
From what I can see, you have a Type III Inland Trigger Housing, which is correct for your serial number.
You'd need to swap out your current:
Hammer, Trigger, Mag Catch and safety to make your internals all Inland.
I found these searching GunBrokers auction site. I know and trust the seller 81MM, he may have everything you need, but I don't know if he'll ship outside the USA. You can contact him through the "Ask the seller a question" option on the auction page.
