Hi, yeah I got the clock from Ebay it wasn't expensive , just search eabay for a 52mm analogue clock and it should come up in your search box,

I went with a replacement clock on my fuel gauge because it was easier to do this rather than cutting into existing circuits or oil lines. But you could choose an Amp gauge.
The point of replacing the fuel gauge with a clock is not because I wanted a clock more about I wanted an accurate reading of the fuel left in the tank. If the fuel gauge was accurate insted of bouncing all over the place I wouldn't change it. However now that we have I', really happy with it.
