'69 Chevelle master cylinder question

[Dion Hildebrandt]

Although I run a 70 chevelle, the masters are the same, I have a wilwood master cylinder with the wilwood front discs with rear drums. The master cylinder is not a 'plug and play' I had to carefully slot the holes that mount on the firewall, and the steel brake line fittings off the master had to be reversed ( rear res fitting goes to the front, and front fitting to the rear). I run the factory prop valve in mine although my car had factory front discs on it. One thing to note is you will probably want to get the wilwood master cylinder mount kit mainly for the pushrod retention deal. The line pressure went up huge from the factory master, although the pedal feel is deffinitely softer, hope this helps.
