white guage face

[canuk7]

Hi all,
Did a search but could'nt anything.
I'm thinking of changing my instrument cluster face to one of the silver ones I've seen for sale on e-bay ( I have an au1 forte.) I have a fair idea on how to do it, but is it a fairly easy change over. Any tips on how to do it would be very welcome. I've seen some on e-bay made by Speed Graphics. Are these a good quality ($70). If not, any recommendations.

Thanks
