No, they're not the same.
Try a Suzuki or Yamaha dealer for the rigging tube flanges - about £20 apiece
Searider elephant's trunks have an octogonal flange which is screwed to the outside face of the transom - they come up from time to time on ebay, or try IBS, Polymarine, or Avon dealers. I think Ribcraft also use the same type of trunk as Avon.
just checked ASAP site and they have them available as singles................for over £20+VAT each
