CA BIG RED there are a ton of sites and video's on the web showing how to repair cracked dashboards, if you are unhappy with the one you bought, try one of these methods, if you like how it turned out, refinish it and reinstall in your truck. If not throw away, you were going to anyway.
I actually plan on doing this to mine when I get to the interior, I have my original and the parts truck I bought, so I do have 2 to get it right.
