I hope that I can help with your questions.
1, Regarding the bag tie in service…If you would like us to do this, you would need to select this option and send us your stocks, either taken out of your old bag, or in the old bag. We would tie it in for you and send it back. Typically this takes about a day to do.
2, Yes, we do send tracking information to you once the order is shipped!
3, Yes, it will come with the T Zip, O Ring and Clamp as well as the elastic tape. If we tie the bag in for you the O ring, clamp and elastic tape will be used.
Please let us know if you have any questions or if we can be of any help!
