Shiprush not retrieving service or package information from Drupal Commerce

I upgraded an ubercart site to Drupal Commerce and most of it is working, but I am having some issues getting the service and package information to import with the shipment. Is there something I need to add to the ShippingZDrupal.php to make this happen?

I noticed that ShippingZDrupal.php doesn't have the information that is contained in ShippingZUbercart.php from lines 225 - 249. Is there equivalent code for Drupal Commerce? Any help will be greatly appreciated.

Thanks!
