Clutch will not engage, worked last week and has less than  than 1000 miles on new clutch.  Fluid levels all topped off.  Any suggestions

This one sounds mechanical to me. If the problem was in the hydraulics the problem would be a clutch not disengaging (pedal down). Do you have any pedal pressure aside from the pedal return spring? Any engagement at all. Does the car move at all when the trans is in 1st and the clutch pedal is up?

Very strange indeed.  Car was running fine last week. Abit of a clunking sound during acceleration but we thought about driveshaft.

The Clutch has release to the floorboard without any pressure.  Had a small amount of engagement to move out of first to neutral but then no shift movement. The clutch was renewed with Motorsport clutch kit and throwout bearing   10/16 . Has very few miles on it since.   Some forum discussions in the past regarding pivot ball, clutch fork issues.

 I'm a bit confused. If you can push the pedal down with little to no pressure, the problem is in the disengagement. Is that we're talking about? That is almost always a hydraulic problem. You mentioned the fluids had been topped off. Was it losing fluid or can you account for the previous loss? If either cylinder is leaking, the area under the cylinder boot will be wet. If the cylinders aren't leaking and the system has been bled properly then the release fork and ball would be the next place to look. I have seen pressed steel release forks crack at the edges and bend.

Sounds a bit like the slave cylinder has failed.  it might be an internal failure without an external leak.  Get one person to operate the clutch pedal, another to observe if the clutch fork is moving.

Without more history it's hard to say.  If the car sat for 10 years then worked for a week after you got it running, is different than it's been a daily driver for 10 years that just got a new clutch.

You can peel the dust boot off of the slave cylinder by hand.  If it's full of fluid you'll know it's bad.  Br careful it might have some pressure behind and squirt.
