Have just finished making up a set of wheels for my 2008 Tarpon 120. Made a few measurement adjustments in the transfer to metric. Tested it in the yard and all working so far. Will test it more this weekend. If all goes well my hearty thanks to you for posting this on the site. You can't buy wheels that fit a SOT Tarpon in Hobart so this was my only option. Really useful instructions. Will report back when fully tested!
