Thanks to the efforts of one of our overseas members, I received a large parcel on a freight truck today.
Bloody Excellent says I.
Upon opening it & found that the description was right on the money. Here's what the package contained.
This is a complete Sunny Excellent GL dash assembly.

This one is the facelift model from about mid '72 onward. It is the 'double hump' version as the facelift model Sunny 1200 GL & GX used a single hump dash. This should solve the metric speedo problem & of course my coupe will now be 20kph faster as the speedo goes to 180kph [112mph] instead of the 1200's 160kph [100mph]

I was also offered a second, very scruffy but complete dash from a Sunny Excellent GX. This is regarded as a parts dash, but in reality, with a bit of work, it will clean up very nicely. The tach will be going into my GL dash, thereby making it a GX one.
This GX dash looks to have been taken from a VERY rusty car as one of the side bolts didn't want to undo, so the dash was ripped from the pillar, bringing part of the pillar with it.

I will make one really good dash from the two & the remainder will become available, however I think that it has already been spoken for. The GX one has the correct twin choke cable choke control.
This will serve very nicely when I slip in the A15 with GX induction.
Ahhh, nothing like a little class to make my slow journey a little more comfortable.
A great debt of gratitude is owed to Matt for all his help.
