The Sutton harness had a number of changes, the first being that the 'perforated' adjuster holes were retained, but the quick-release twist buckle was added, then the whole lot changed to the later style.
Neither of those are totally 'Typhoon' for late fitting, but the upper one is closest. It should have the 'Y' strap which went behind and to the lower frame of the seat, or at least a shorter 'tail' strap.
However, use the upper set, and 'bury' the long tail strap behind the seat - it won't be seen anyway.
