Mating Plymouth 3 speed to P25

[duly]

Like the title says I am putting a 3 speed on a P25 and need some guidance. I have the service manual for Dodge passenger car 1949-1952 but it is not much help and this is a Plymouth. If somebody can point me in the right direction for a quality service manual I would appreciate it or somebody can walk me through it or just some advice would be great. This is my first experience with manual transmissions so any help is appreciated. My main question is that the clutch release bearing inside the bell housing? Clutch and flywheel are still in the bell housing attached to the motor, looks like only the transmission was removed. 

 

Thanks

Yes, that's the release bearing in the first picture.  I would pull the bellhousing, clutch and inspect...
