Have any of you used these white face gauges from ebay?

eBay Motors: i377 91-94 NISSAN 240SX S13 WHITE FACE GLOW GAUGES (item 300046123636 end time Nov-08-06 23:06:40 PST)

Thought I would install them since I have the dash out of the car to replace/clean the carpet. If you have installed them, was it a pain? Any tips?
Thanks....
