Anybody use a dash cap to fix their pad??

i had a dash cap on my e body cuda, i wish i just left it alone with the crack in it. the sun warped it something awful. then the cold cracked it in about 4 places. would have tried to take it off, but had to scuff the original dashpad and glue to install it. of course the ebody dashes pads are rather large and curvey which doesnt help things.
