Looking over my spare parts and a closer inspection of the clutch
hydraulics revealed that I can't get enough travel out of the slave
cylinder.
I measured the the master cylinder stroke ~ 1 inch but slave cylinder
is ~ 1/2 inch. When assembled I run out of travel with the slave piston
so it only travels 5/16- 3/8 inch.
Since the clutch master is at 5/8" and the slave at 7/8" (I think) it
would equate to less travel but not that much.
I have not yet pulled the trans but planning to do so shortly.
Thanks for the suggestions

so I'm moving a little slow)
