5. Before we get ahead of ourselves, I need to drill a hole in the clutch pedal arm so that I can mate it to the Wilwood hydraulic master cylinder. The Lokar pedals are designed as a direct, OE replacement part and as such, are designed to actuate the stock clutch rod linkage via the clutch rod lever that installs opposite the clutch arm. I’m going to mount the clutch master cylinder on the firewall next to the brake master cylinder, so matching the hole in the brake pedal ensures the two master cylinders are mounted level on the firewall. It also works out that the ratio for the brake pedal works out for the clutch as well. With the pedals aligned, it’s a simple matter of using a transfer punch to mark the clutch arm before it’s drilled to size.
