I used what is basically a GM dual master cylinder from MP Brakes. The thing that I did was to order one with the line outlets on the opposite of a stock unit because when you mount the unit either on an altered master cylinder bracket or on a new bracket (I made a new one), the lines on a stock unit exit the master cylinder right up against the transmission. Yes, you can probably get them in there, but I figured it would be a whole bunch easier to bring them in on the left side of the master cylinder just as the stock ones enter the stock unit. So far, it looks like it is going to work fine.
