you can glue a dash mat on it.. fixed.
the state of the other trim is pretty rough, sure it's not worth finding another interior or do you have good trim for it?
you can get them redone at huge expense ($800 rings a bell)
i've seen (and i'm likely to do similar on My gemini one) slicing out the high part of the crack so it's a bit lower than the top, mixing up some fibreglass resin and laying it in the crack , then bogging over, sanding and painting the whole thing .
depends on your budget and if you care if it' cracks again(i think it's so brittle now it's likely to crack again anyway unless fully recovered)
