Fixing an LE 500 oil temperature gauge

Thank you so much for a comprehensive guide. On my LE500 I had a temperamental oil temp gauge were it went from displaying a temperature to zero. Took a punt that it was the temperature gauge and bought one from Rimmers that had a silver face and used a black decal kit from brown and gammons to replace the silver face.
Luckily the new gauge had orange lighting leds.
Used your guide and hey presto I now have a working gauge.
Now working on my key fob operated electric boot release

Brilliant how to CJJ.
Just used it to replace my black faced LE500 oil temp gauge using all of an older silver faced gauge, just by changing the black face, and keeping the needle from the silver gauge. Easy 😂
Didn’t need to make the hole much bigger as the needle spindle was small enough to use the facia almost as it was. For the hole enlargement I tightly rolled up a small piece of 600 grit wet and dry sand paper - did a really neat job.  
Also the LED was near enough the correct colour so didn’t need to swap that over. 
I now have a working gauge - many thanks!!
