Hi Guys, hope everyone is staying safe.

I have a 280z without a brake booster. Checked on Orielly's and they told me there are 8.5in and 10in version of the booster. Which one does the 77 use? Mine is an automatic transmission if this all matters.

 

Early Zs had 7". In '73 thru '78 they went to 8.5".

I can't see an auto using a larger booster but I've never owned one. Go to amazon.com and use their "will it fit" tool.
