I removed the dash last year, I posted some pics. It took me about 2hrs. to remove and about 4hrs. to replace( I took my time!)
I used epoxy to mold it back into shape and clamped it down till it cured. I used regular 10 min. epoxy but in retrospect I should have tried the epoxy that's made specially for plastic ( bought it in an auto parts store) I've used it on other applications and it worked fine.
Do a search for the pics. under dash removal.
