Call 1.626.442.8522 and ask them for a blow by blow way to replace them.
Wow looks very bad from the site. I just replaced a speedometer cluster and it was a bad job the wire connecters are very hard to get off. Any to much force and you will break something. Good Luck
use search bar type 200 toyota celica gt then when you get to page type gauge cover might shock you on the things you can find when you know the name.
I would prefer to use an Instrument specialist that way you order the look and it's guaranteed.
