Clutch cable adjust-tried everything-pedal has to be pushed all way to floor Options

[jjs3rd914]

72 914-4 with 73 side shift tranny and shift linkage. Only 5000 miles on new PP, TO bearing, and clutch disc. Cannot remember is had flywheel surfaced as was 5 years ago. All new plastic cup bushings etc installed on clutch fork.

Since installation have had to push pedal all way to floor to get into gear. Have read all the past many threads on clutch cable adjustment. Have set the "1/2" inch free pedal play by adjusting the two 11mm nuts on cable at tranny and have to keep pedal absolutely nailed to the floor to shift with out grinding. Even went from 1/2 inch of free play to zero by adjusting the 11mm nuts tighter and it has made little difference.

Anyone have any ideas? I am leaning towards the ball pivot not having enough of a washer spacing. Cannot remember what we installed. Dumb as knowing this could answer the issue.

Clutch tube is solid, pedal cluster rebuilt, new clutch cable. Any ideas other than pulling tranny.

Some past threads say to forget the free play and to adjust the cable tightness until get clutch engagement 1/4 to 1/3 the way up on the pedal from full down. I am reluctant to do that as I indicated we already adjusted for zero free pedal play and by going even tighter would start to have clutch slipping?

Thanks
