As I am putting my series 1 240z back together I found i have a two 280z clutch and break assemblies. I can get it installed without issues as i have a 280z steering column and a 240z column. I do understand there are changes with alignment for the fireware because they increased the size of the brake booster....

My main question is, are the pedals further back in the 240z assembly vs the 280z? with the 280z version installed i feel like the pedals are further away from the firewall than they should be. I'm 6"1 and my legs are more cramped than I remember being in the 280z. I have moved the bump stopp all the way out to push them as far as possible but they are still too much forward.

Go to CarPartsManual and compare the two different model p/n’s.

Thats a great source of information, thank you! I do have paperback manuals for the car but nothing is showing measurements.


I feel like the pivot point for the 240z and 280z are different lengths away from the firewall.

I had a look at a 240 and 280 pedal box, and the pivot points on the 280 box are at the same place as the 240. The rubber pedals are closer, but that seems to just be the stop adjusters are different.

Thank you. I decided to change out the stop bumpers and make them longer so they are back further. I have yet to hook up the hydraulics yet. hopefully i will have enough range to allow the clutch to work. We will see! Thank you again.
