Tremec TKX first cuts

For you guys that ran the hydraulic clutch, did you have any issues installing and aligning the master cylinder to clutch pedal attachment? If I align the master cylinder centered in the hole in the firewall, the rod from the clutch pedal doesn't really have a straight shot into the master and the instructions are pretty clear about ensuring it goes as straight in as possible to avoid failures. Were any modifications necessary?

Don't worry about centering the master cylinder with the hole in the firewall. The rod alignment is what matters, like you said. My master is completely off center of the OEM firewall hole (but perfect rod alignment). It's definitely tricky to do, especially alone with no help, which was my case. I spent at least an hour checking over and over again, climbing in and out of the car, to make sure the position was right before drilling the mounting holes.
