Pressure plate problem

Bought a hays street strip clutch kit for my 1970
Swinger and I'm having trouble getting it into reverse and
1st gear I talked to hays because I extended throw from 5 1/4 to 6in on pedal
And have replaced every nylon washer clips internal shift lever ball and spring
They tell me my pressure plate is not adjusted right and it is not releasing the clutch when I depress the pedal I have plenty of throw.
:pukerigh:
I have physically adjusted throwout bearing by sight and still can't get it into gear smoothly I have less than 500 miles on car so I pulled every thing apart
Sfi bell housing (fun) and I'm sending plate and clutch back to see what they think any body have similar problem please help!!!

Thanks steve
