Arne, I have a 76 280z 2+2. Can you please confirm this with me. The FSM calls for about 0.387" ( or close to it, I don't have the FSM right now). This is from the face of the booster to the tip of the rod without the spacer.If I add the spacer, the tip will be inside the spacer following this length. Now, Haynes manual is calling it at 0.138-0.157" from the mounting flange and the end of the push rod. What I did was o.387" from the face of the spacer to the end of the push rod. Also, with this set up, I don't have to adjust the push rod lenght anymore. It came with that lenght. Is that wrong?
