Good afternoon all!

Here is what I have.
99 WS.6 with the 6 speed manual. Adjustable McCloud Master Cylinder. Ram 402 and I believe a 4340.

The pedal feels like it is stepping on rocks. BAD noise at anytime, slight change with pedal engagement. Fuild is cooked.

I am about to order parts, I need them quickly, but am not sure what to order. Of course this time I am going to do it right and order the shim kit of the slave, but need help with the actual parts that are bad.
I was told it is the release bearing. Ok, now looking at GMdirect, I see the release bearing listed, also a slave cylinder listed. Are these same? What I mean is...Does the slave cylinder come with the release installed?

Rather, what should I be ordering for this job.
