The same problem being: I adjusted the nut to the very end of the upper clutch rod so there was no room for further adjustment, and I still had to push the clutch all the way to the floor to shift gears. I would often hit the bright light switch by mistake.

After much much discussion (check the archives!!!) it was determined that I needed a longer clutch fork pivot ball. GM makes 2 lengths, a short one and a long one. Some folks use an adjustable. Me being bubba opted for a longer clutch rod.

Did I read your problem correctly? If so, check this:

PRNDL, Replacing the lower rod seems like the easier fix. This will help to release the clutch when the pedal is pushed down, will you still have enough adjustment for free play in the pedal?

That's not a fix, it's a bandaid. The correct parts will work with the stock linkage. Something is not right and should be fixed.

That's what I'm afraid of. I was hoping to avoid another tranny pull. I may just order a vette clutch set from Zip, Mid America, or Corvette Central. I tossed the old clutch, which appeared to be original. I kept the TO bearing, which is the short one. ( 1 1/4"). I almost hope that I find something that I did wrong, so I know what to fix.

I know this has been mentioned before, but you have a geometry problem. If the adjustment is at the edge of its range you'll have reduced "throw", which is exactly your situation. You need to make a change to the geometry (different pivot or throwout) to bring the adjustment back to the center of its range, which will increase the throw...

With those symptoms, it sounds like the clutch fork is not placed correctly in the groove in the TO bearing. It is extremely important to ensure that the clip is positioned INSIDE the groove of the throw out bearing. The following url shows a good picture of the correct installation:

If the clip is on top of the aft flange of the TO bearing, you will have problems.

I struggled with the same problems for quite some time. I ended up getting a adjustable pivot and somehow then managed to bend the adjustable rod that hooks on the pedal the zbar. Took it all out and threw in a hydraulic setup from a 1 ton chevy. Cost $100 bucks and works like a charm.

Your TOB should be in the fork like this:
