2007 yaris passenger airbag recall time to complete??

[Lightrfire]

So I dropped my yaris off to get the airbag recall done. They initially told me it would take 2 hours and when I got there they told me it was a 5 hour repair and the car would need to be left overnight! Wtf! They said the dash needs to be removed in its entirety to change it! Is this true?? Why would they quote a 2 hour repair previously then? I'm worried they will mess up my tach install and radio. Anybody else do theirs yet that has any input on this?
