Gl1200 Intersate Tachometer size

[rodvien]

Hello,
Was wondering if anyone with an Interstate could tell me what the diameter is of the tachometer face dial.
I'm building a custom gauge set and was hoping to use the tach and speedo from an Intersate.
Thanks in advance.

3½" as close as I can figure. The gauges are set back from the glass so you can't really get an exact measurement.
I know I have a spare gauge somewhere. If it really comes to that I'll see if I can find it.

Thanks very much for your quick replay and the info.
Sounds like it will work for me.
