I cracked the clear plastic in front of my instrument "pod" and Vauxhall list two different ones.
90589499 - costs about £10
90589500 - cost over £30
The difference? The tabs that hold it in place are in different positions and nothing else.
I don't need to say which on I needed!
The only difference I can see is that 90589500 is for the cars with rev counters and 90589499 is for the few without.
I'm going to be bloody carefull when I fit it this weekend
