Question Single mass problem

I bought a 95 F350 7.3L Power Stroke, DRW. I thought the clutch needed to be changed, cause it was grabbing at the very bottom of the pedal.
I finally got to pull the inspection plate, and to my surprise the clutch looks brand new, and I noticed it had been converted to the single mass flywheel.
I have looked for anyway to adjust this before I mess up this tranny, because it is hard to get into gear, and sometimes grinds, but the clutch pedal is all the way on the floor, and I hear the slave start moving as soon as I start pushing the pedal. What would cause this, and is there something they didn't do, or I can do to bring it back to the top of the pedal?

First, check for the usual culprit, the infamous bushing at the clutch master cylinder rod end. Make sure there is no play there due to a worn or missing bushing, worn master rod end, and/or worn linkage arm stud. You can also look to see if there is any play in the brake/clutch pedal mainshaft bushings. After that, measure the stroke distance of the clutch slave cylinder (off the top-of-my-head I think the minimum is 11mm, but I'll have to double check). If that is off, you may need to reindex the lever arm on the mainshaft, you could have hydraulic problems (or need to bleed the system), or possible someone replaced the slave with the wrong one (the slave must match the master). Cheers!
