Interestingly it is recommended to glue them in place when replacing, in which case I see little point in purchasing new replacements.
I've got to go back into the instruments at some point to replace a screw which has escaped from the speedo dial and is rattling around behind the glass... Any suggestions for an appropriate none permanent adhesive in the meantime?
Cheers
