With the internet available for the past 10 years in the AFP. They can look up parts supplies anywhere in the world.
But there may be a problem when procuring parts, other than they won't accept credit cards or paypal from the Philippines....
Try it your self. Search for prices and availability from suppliers. Factor shipping and etc. If you request CIF (Customs, Insurance and Freight) included in the price. It may be quite different. Particularly when the parts are inspected by Phil Customs. So you may have to select your port of entry. Subic, Clark, South Harbor, etc.
