1994 Subaru Impreza WRX Sti Hatch V1

Hi everybody, I recently bought a 1994 Subaru Impreza WRX Sti and have decided to rebuild it and restore it to its original condition. But that is easier said than done. The car is mostly original but a few parts are needed. Is there a website that has new, refurbished or replica parts for old Subaru's like mine? any help will be appreciated
