All Permalinks different after importing from Blogger

I just imported my blog from Blogger to WordPress. However, the permalink structure did not import, so now all of my permalinks are slightly different, resulting in thousands of broken references and links.

For instance, in blogger, a particular post was: http://www.graspingforobjectivity.com/2009/09/carnivorous-creations.html

It came over in WordPress as:
http://www.graspingforobjectivity.com/2009/09/carnivorous-creations/

I often reference myself within posts, as do many other posts, blogs, and forums. As of right now, all of those links are broken.

Is there a way to re-import and keep the permalinks exactly as they were?
