This is quite different from the "old" one, so not a direct swap, but I can cut you one if the old types if needed.

The whole belt drive with tensioner is redesigned, also it's now made from 16mm alumec, with SC's countersinked into it, revised mounts, and an added 3rd mount stopping it from lateral/horizontal movements (observed in engine-dyno sessions) under max load, one-piece oversized main damper/pulley + oversized SC-pulleys, 7rib (or 8 if proven needed)
