Anyone successful with removing the tach and speedo with a full face dash cap in place? I need to remove the speedo to repair or replace. How about removing from the back instead of the front?

If the 23 mm doesn't work. Find a ~10 mm and cut a notch in it with a grinder so it'll sit over the wing. I find it works well.

The 280Z's don't use the wingnut.  There's one screw in the top of the ring in front of the lens, and one in the mounting bracket, dead center behind and underneath.  Plus, at least on my 76, there is a bunch of clutter around the back of the gauges.  Not much room at all.

 

Good suggestion, but wrong car.

Wingnuts in my Z were about 19mm. Taking out the tachometer was a bitch, but taking out the speedo was even bitchier. The upper wingnuts were accesible, but stuck as F. Tools that i found most usable were this "pipe" type socket and strong fingers. I bust all my knuckles, almost destroyed my thumb trying to press the wingnuts open, my hands look like i was in a fist fight but it is OUT.

 

 

Borrowing this thread one more time. Ive attached new speedo and replaced all the bulbs. For some reason only the blue light indicator works when i switch to long lights. Do i need to ground them somehow or what? I have no tach on place.

To clear out the one above, lights that should illuminate speedo, wont work.

Ah, they ground on the holding brackets. No worries.
