clutch adjustment problem

clutch starts to engage 3 in off floor

This should be more than PLENTY. Can you get it into reverse without grinding?

If so, then it's not a clutch problem, it's something else, bad syncros, wrong lube, a bad bearing someplace -- including the pilot.

If you cannot get it into reverse at a stop without grinding then I'd bet money it's a disk or pressure plate trouble, RATHER than linkage
