All my letter said was that they would be asking for documents to be faxed but there was nothing specifically asking for anything except the dental record thing. I had the same situation, I just grabbed an ACP and we came up with an endorsement for the logbook. Instead of a stamp I photo copied his business card on each page of the logbook. Luckily I had a PC about two weeks before my second interview so I had the guy endorse my logbook. He looked at me funny but he did it.
When are you going? PM me with the info.
