Power Brake Booster 7" Dual Diaphragm Racing 240Z
New 7" dual diaphragm power brake booster for Datsun 240Z 1970- early 73. If you need more power assist but do not want to modify your 240Z firewall, then this is the booster you need. We put together this custom booster for the 240Z because the 240Z can only use the 7" diameter booster which are no loger available and the 240Z has a different mounting bolt pattern than 1974-78. We use a new yellow zinc coated 7" booster with an extended diaphragm (acts like a larger diameter booster) and provide adaptor plates to work with the stock firewall bolt pattern as well as retaining the stock master cylinder. New rubber gasket seal for the firewall is included. No modifications required to the firewall. This booster sticks out far enough that there may be some interference with the left wheel well, may require some clearancing of the wheel well. You will need to reuse your stock adjustable master cylinder rod.
- Dual Diaphragm 7" Booster customized to fit 70-73 240Z
- Billet Aluminum master cylinder adaptor plate
- Rubber gasket for firewall
- 3/8" clevis
Late 1973 240's may have a different bolt pattern on the firewall. If you car was originally equipped with a 7" booster than this one should fit.
