Diaphram street clutch finger movement distance?

Gentlemen! 68 dart 360/833 change over from auto. Everything mew/rebuilt from Brewers
with all new component z/bar fork,pedals #734 bellhousing//hurst comp new shifter. Everything bolted up right. Clutch new 10.5 23 sline disc centerforce street clutch. Clutch
disc would not release when running. Thought I had disc backwards. It was on right.
So put it back together. Checked throw out bearing and I think clutch rod throw out
brearing not moving deep enough to move fingers deep enough to push fingers far enough
to release clutch disc! What is your thought? Everything is new from brewers!
