Borg and Beck type clutch with hydraulic throwout bearing?

Hi, I am installing American Powertrain hydraulic throw out bearing on a 1971 Scamp, the car was originally 318/auto, I got a pedal conversion from Brewsters. In the power train instructions they say a 5 or 6 to 1 pedal travel is optimum. Did you use same angle as oem linkage? etc. ?? Looks like I will be able to mount slave at same locaton as mechanical linkage hole in firewall. American powertrain technical assistance is really non existent. Any tips would be appreciated. It is going to be a 360 with a A833 four speed, I did order clutch and pressure plate from them also Thank you, Dave
