Many forums that I belong to have a section of STICKY set up just for this purpose. Broken up into categories just as you are showing here. This could also work for a Subie section: engine/drivetrain/ cooling/ cable shifter/ wiring. More stickies for other water cooled conversions, different suppliers to all of our mechanical, electrical, body and other 914 needs.
Makes it a lot easier to find in one place
