The order is 8130.2 G There are some big changes between the two documents. I posted a link in the thread earlier. One of the changes is for a placard to be visible to the pilot with certain limitations.
If the former owner or home airport is not specifically mentioned in the operation limitations (I have seen a lot of poorly written ops limitations from FAA inspectors that don't follow the guidance) AND you are satisfied with the old limits all you are required to submit is a new program letter. The FSDO "should" upon receipt of your program letter ask you for a copy of the airworthiness certificate and maybe a copy of your latest condition check to start a file. Review the 8130.2G as the program letter requirements have also changed.
The 8130.2G limitations for gliders are a lot less restrictive over older operating limits (such as removing the 300 mile operating limit). You might consider asking for new operating limitations and they will also issue a new airworthiness certificate.
