I agree. I went with hydraulic (mainly due to the hype) and I had geometry issues due to the slave hitting the inner fender, then I had lines leaking, it was a mess.
You should have a TO bearing with your new clutch, and if you have the fork, set that in place. You can install all of that in the engine and then mate up the trans. Install both and then just call Brewers or send him an email and he will give you a quote for anything missing. He's great to deal with.
