Hello,
In France, I sell VDO instrument kits for GTA's. I have developped and manufactured kits to replace the front ashtray (2 instruments), and also din kits (3 instruments).
Here is an example of an ashtray replacement kit, with voltmeter and oil temp. All the parts on the picture are fitted.
And this an example of a din kit, with voltmeter, oil temp and watch.
In the GTA, with the turbo boost instead of teh watch....
Please tell me if English GTA owners would be interrested by those kits, because for the moment, the installation guide only exists in French!!
