The Opel Kadett GSi from the eighties was optionally equipped with a digital LCD instrument panel. This was a very cool feature in those days and it still is a cool thing to see. The Astra GSi was not available with an LCD instrument. So time to make an old Kadett LCD fit in the Astra!
We start out with a bone stock Kadett LCD and take it to bits:
We also need a speed pulse generator that bolts on the transmission to generate the speedo signal and we need an oil pressure sensor:
Then we need to hack up the front mask of the Astra instruments to glue in the mask of the LCD display:
Then we need to modify the odometer. The reset push pin is in a wrong position to fit the hole of the Astra cluster. The way to solve this is replace the reset pin shaft with a longer one that i ripped out of an old speedometer. This way the reset pin can be relocated exactly on the right spot for the Astra cluster:
Then it is time to put everything together and make a backplate which adapts the Astra connectors to the Kadett LCD Panel:
