How bad is the combo meter repair

So I’m planning on doing the combination meter myself since I got quoted 1k for it. My main concern is I’ll habe a remove some airbags and put them back, what can I do to safe guard myself during removal and installation. And how can I ensure their function will be preserved in the event I ever crash. Also is there a good source for the trim pieces and vents I’m going the break while doing this.
