I'm not sure if this helps or not, since I have an automatic, but I used a flexplate for an '85 when I changed my one piece rear main 305 for a 2 piece 350. The Autozone website lists a hydraulic slave cylinder for both '85 and '86, and they have the same part numbers. That implies that they were both hydraulic clutches. They list two different flywheel part numbers for '85 and '86, so it sounds as though you could just use the '85 flywheel with the new engine.
