I had read another 5.0 build thread on Mazda Trucking, I believe he is a member on here too... RG2200. He linked me to this site for the bracket and slave. Pricey, but the installation was easy and they had very fast shipping.
He said he upgraded his master cylinder to a larger size, but other projects I have read through that did the same conversion said their stock Mazda master was fine. I haven't had a chance to hook mine up yet. I just need to buy the braided stainless line to go from the master to the slave.
Overall, there is a decent amount of information on the subject if you check Google for T5 hydraulic conversion kit.
