Help! Restoring a Colt Lancer 1979

We're trying to restore our old Colt Lancer 1979 four door. Medyo napabayaan and ninakaw na yung parts. Nahihirapan kami to find replacements na used or brand new. Anybody who knows a surplus shop na baka may parts? Even sa Banawe wala na halos. Pinapahanap din ako ng manual or catalogue nung parts and I've been searching online pero wala.

Thanks in advance guys. :grin:
