Restoring an 87' FC3S Turbo. Bought it with a few mods and unfortunately the previous owner ripped out the AC system from the firewall forward. Have been accruing parts lately to put back together. However, I can't find detailed AC system diagrams, photos and especially workshop manual with detailed AC info. Have downloaded a free PDF that covers all the major FC3S systems but does not include the AC system. Really would like that Mazda workshop manual chapter before I go too far down the path. Any ideas on where I can find, download or purchase for a reasonable cost?
