This billet adapter and larger bore clutch master cylinder will allow you to do a simple bolt-in installation.

The only modification you need to work with an OEM pedal is to drill out the hole with a 12mm or 1/2” bit to get rid of the keyway in the pedal. From there the clevis will slide in snug.

You will be required to reuse the forward most OEM bolt that holds your clutch engagement switch.

If you are using your OEM brake master cylinder reservoir, you will need a -4AN 45 degree push-lock fitting for your rubber line to feed the clutch master cylinder.

E36 SPECIFIC: You will be required to remove the assist spring on an E36 pedal arm before using. The firewall is very close to the master cylinder on E36, some massaging of the firewall may be required along with a banjo bolt for the outlet port.
