Speedo drive

[Mcsybe]

I plan on putting an astra mk2 gte digi dash into my nova.

I have the dash, black n white plugs in the back and the digital dash and I have the transducer. I don't have the speedo drive on the end of the transducer (the toothed cog thing).

Can I use a speedo drive from else where or will I need the exact one that would of been on the end of the transducer when it was installed in an astra gte?

The engine in my nova is a c20let with an f28 gearbox.

Any advice would be much appreciated.

Thanks all!

If your F28 is a mechanical speedo drive you need to fit the black toothed speedo drive to the differential from a F20 gearbox

the F28 used a blue ring with more teeth and isn’t compatible with the digi drive speedo drive or standard nova speedo drive
