lcord Posted November 12, 2021 Share #1 Posted November 12, 2021 Hello I have an early 1972 240z (5/72). It states that those stock brake boosters were 6” in diameter. I did a search for a 6” kit and didn’t find anyone that had them. Are they available out there or are they custom built on request and that’s the reason they don’t show up on the website. Thanks Link to comment Share on other sites More sharing options...
siteunseen Posted November 13, 2021 Share #2 Posted November 13, 2021 I bought my 69,xxx booster from amazon.com and only had to paint it black. Works great on my early '72. Link to comment Share on other sites More sharing options...
lcord Posted November 13, 2021 Author Share #3 Posted November 13, 2021 Do you have a part number and manufacturers name? Link to comment Share on other sites More sharing options...
lcord Posted November 13, 2021 Author Share #4 Posted November 13, 2021 I went to the Harmon classic brake site as well as to the Power brake exchange website and there’s no mention of having a 6” kit. Any help would be appreciated. Link to comment Share on other sites More sharing options...
Patcon Posted November 13, 2021 Share #5 Posted November 13, 2021 My memory is failing but I thought the smallest one was 7". Maybe call Harmon classic or PBE and they can walk you through measuring and identifying yours and whether they have parts for it Link to comment Share on other sites More sharing options...

conedodger Posted November 13, 2021 Share #7 Posted November 13, 2021 Do you have a brake booster? Box it up and send it to Power Brake Supply. Get it back 3 days later like new. Link to comment Share on other sites More sharing options...
dutchzcarguy Posted November 13, 2021 Share #8 Posted November 13, 2021 That 6 is a typo i'm sure.. the small 240z brake booster's are 7 inches or 178 mm. diam. 1 Link to comment Share on other sites More sharing options...
lcord Posted November 13, 2021 Author Share #9 Posted November 13, 2021 Thanks so much for everyone’s information. I’ll send it off to Power Brake Exchange. I was looking on the carpartsmanual.com website on the master vac for the 240z and it showed that the early 1972 240z had a 6 inch size master vac.
