Hi Buloy
I'm here on holiday in Manila at the moment, I live in UK but my wife and I are visiting her relatives in Cavite.
I've found Mitsubishi Genuine parts in Megamall very helpful in locating some essential parts for my Lancer EX2000 in UK, perhaps they may have a manual, or access to one.
I've decided to buy a Box type within the next year in Manila, and ship over a 4G63BT Engine, loom and auxilliaries from a wreck I have in UK. I hope to be sending them within a few months, so if you have not found a manual by then, I'll try to find one here in UK and send it in the same consignment.
If you PM me the exact details of the manual you want I'll try to locate one in England.
Regards
Pete
