Gauges

I received a NOS late/early gauge for the fuel cluster in trade for an early ignition from a club member last year.  I took the gauge apart and swapped out the button from the late gauge to an early button (without the dimple).  I'm still going to pull the needle and swap out the gauge face since the early cars have wider lettering than the later cars.  I want it to look as 'original' as possible-especially since I have the parts.

This is how the gauge looks now.  The center gray button says 'early' while the lettering gives it away as a 'late' gauge.  The tach is a repop version made from a clock.  I have to repaint the grey trim rings so they match-but I have to wait for the speedometer to show up....this is what I'm hoping to find/restore:

This is the speedometer I want to put between the two gauges above.  It's a bitch to find in anything other than 'trashed' condition.
