I've taken the oil temp and clock out as I wanted to change the bulbs to blue LED's to match the other instruments, shock horror they are sealed units (its a TF, F's aren't apparently) with internal LED's already.
I have a mate who will solder new ones in but how do I open the gauge up, is it a case of gently peeling the bezel back to get it off, I've looked at the "How To" but that shows the gauge innards already out with no explanation how.
