disk brake conversion/master cylinder upgrade

I have a question for the masses. I have a '67 CJ5 with Dana 27 front and Dana 44 rear. I am just finishing up my front disk brake conversion and am leaving the rears drum for now. I also want to upgrade the master cylinder to the dual reservoir kit from Herm. I have emailed him several times with a question and he wont respond to anything but how much is it going to cost. This is a little frustrating. He asked if I needed a proportioning valve with it as well. I asked him if with his kit, do I need a residual valve and a proportioning valve, or do I need either of them, but he wont answer. So, any help from the forum would be great. I'm not sure what all I need for the change over.
Thanks!
