Fixed the problem. The bolt which connected the shift fork to the linkage had come loose . That added a ton of slop which prevented the clutch from fully disengaging.

I have about 2 inches of thread left on the adjustment rod so I thought I could move the nut towards the radiator to bring the engagement point up off the floor. After moving it about a quarter inch, the problem got far worse. It wouldn't go into gear at all with the engine on and reverse still made the grinding. I moved the nut back and the forward gears are still kinda notchy.

But if I go the other way, it'll theoretically engage more when the pedal is on the floor. I'll try it just in case.
I'm open to an adjustable pivot, but I am not sure how to tell I need it.
It grinds even after going from 1st.

Was the throwout bearing replaced with the clutch?
It it the correct height (length) for you application?
Normally, between throwout bearings and clutch fork studs, you should be able to get most off the shelf clutches to adjust properly-
GM had several length fork studs they used in various models over the years.
If the stud length is your issue, I'd try to use one of the GM studs vs the adjustable ones. I have yet to find an adjustable one that has the proper sized and formed head on the stud to fit the forks properly.
Most are too small and the fork retainer clip won't fit/hold properly.
Just my .02

A new throwout bearing was installed and I assume it was the correct one, but that is an unknown right now.
I'll keep that in mind and get a couple GM studs to try if it comes down to that.

Here's a link that will help you confirm if your bearing is installed on the fork properly along with other adjustment information.

******** Fixed *************
The bolt which connected the linkage to the fork under the car worked its way loose. That added a ton of slop to the linkage. I tightened it and now it works great.

Thank you for the link! I used it to verify the fork was properly installed.
