I was curious... If I ever wanted to replace the guages in my *soon* to be 280Z (2 days now hehe) what sizes are the guages?

I have noticed that several people have just gone in and replaced the original guages with new ones...

and I'm not really interested in the overlays..

but what are the sizes of the Speedometer, Tachometer, Clock and Fuel and etc.? *size as in diameter and depth???

And maybe if you don't mind... does anyone have the model numbers of the guages like from reputable companies like AutoMeter or a dependable place?

Example...

I know MSA carries autometer gauges for the Z.

I wonder if those are a straight bolt-in installation or if there are modifications required to get them working correctly. MSA sometimes says that devices like this can be installed, but, they fail to mention that you need to make changes to the system so they'll work correctly.

Anyway, I'm simply ASKING if this is the case with the MSA guages listed on that catalog page. Anyone know?

Anyone know what size autometer gauge will fit the triple gauge holes?

2" ?
