you might look in bbs.legacycentral.org for the parts diagrams. I got them off of there. I just went into the local dealer and ordered every section of pipe that goes to the PVC system, and other parts of the intake. Boot B was the most expensive at like 80 bucks.
Try getting all the part numbers together and send a PM to Subie Gal. She gives decent discounts on parts. She also ships orders out hella fast. And she can also go over the order to make sure you have all the parts.
I tried using some universal hose for some sections but it just made things harder. I still have some universal hose going from the block to the PCV because I didnt have my parts and needed to get the intake manifold back on.
