Note:  This kit is an aftermarket solution for adding power brakes to a manual firewall.  It is not intended to be a direct installation or OEM replacement.  Due to changes in production in certain years, your car may require modifications for this kit to install properly.  This kit is intended for mounting a universal power brake booster in place of the original master cylinder firewall location.

Windshield washer reservoir may need to be moved to the other side of engine bay if installing on A-Body.

Safety comes first.  Any brake service should only be performed by persons experienced in the installation and proper operation of brake systems.  It is the responsibility of the person installing any brake component or kit to determine the suitability for the particular application.  After installation and prior to operating vehicle, brake function should be tested under controlled conditions.
