I ended up buying a setup from this guy. He makes the brackets to fit several different trans. He sells them and also the slave cylinder so I got both from him. Back then they were $110 for the bracket and slave and pretty much a bolt on for my tko trans.

I remember the bellhousing being used made a difference to, some aftermarkets got in the way. Factory aluminum worked and I know quicktime bellhousings worked great to.
I am using a wilwood master (remote reservoir type), 3/4 bore. You can either buy the expensive Wilwood reservoir or get a $2 like I did from a scrap yard. I used a clutch reservoir from 1993 - 1994 Ford Ranger Clutch Master Cylinder for V6-245ci 4.0L. Basically just went looking under hoods until I saw a small reservoir I wanted. You can see the small reservoir mounted to the firewall
Then I used the above slave and bracket.
I am using a longacre hyd. clutch line kit, this one exactly http://www.summitracing.com/parts/lng-28050
The fun part was bleeding it. Man that was something else.
I have not talked to the bracket guy since 2010, not sure if he still does them or not.
So in a nutshell I bought the bracket/slave cyl from Bill, got a longacre line kit, a junkyard fluid reservoir (small one) and a Wilwood master cyl.
Drilled a hole in the firewall and mounted the master where I had room. Easiest way to attach to clutch pedal seemed to be by the picture below. Will clean this up, it was a prototype that has worked well, and not visible to anyone anyway.
Mounted the small reservoir to the firewall and added a hose barb fitting to it for the rubber line.
Installed the bracket, mounted the slave cylinder, adjusted the slave with the trans fork per the instructions, started the bleeding process. it took a while to figure out the adjustment on the fork, and the bleeding process. Finally got it figured out, works great!
As for the slave cyl, the part # for it is a Wagner F124279. it fits a number of 90's Isuzu pickups. So if you have to make your own bracket for your application, you could try getting one of these slaves and determine a bracket design that would mount it correctly to operate the clutch fork.
If your going to run a T5, have a look at these for setups and brackets
