I did it this weekend to mine....the how-to above was right on.
I used a heat gun and a large rubber mallet to push the plastic in. It worked really well....I used a mallet because I wanted something that didn't have sharp edges that could pontenially rip through the plastic once it's soften up.
It took about 10-15 minutes to do it. I can snap a pic if you think it would be helpful.
