I want to order a spare base hardware piece for my Aspire Nautilus. The accessories page also show the connector and insulator ring as separate parts. Are those parts included with the main base hardware or do they need to be purchased separately? I have asked this question through the "contact us" link as well as a direct email to the support address but both inquiries have gone unanswered. I would also like to receive disassembly and reassembly instructions for the base hardware so I can rebuild it when parts begin to fail.
