No, a 1966 slant-six engine and a 1982 manual transmission are highly unlikely to be a direct bolt-up match. The bellhousing bolt pattern, input shaft diameter and length, and clutch linkage or hydraulics will almost certainly be different. Even if you could find an adapter, the differences in engine and transmission mounting points, and the overall drivetrain geometry, would present substantial challenges.
You'd need significant custom fabrication to make them work together. This would be a major project requiring expertise in engine swaps and fabrication.
