Gary - IMV it's a no-brainer.
While you can DIY fit, I would get a dealer to do it, as getting it optimally set up (gap between the Tranquillity plates + LP12 suspension adjustment - latter more than likely IMV), isn't straightforward e.g. more weight is taken via the suspension and it's likely a suspension/platter ride height adjustment will be required.
On the latter aspect, one must be mindful that the suspension on many LP12's isn't 'level' when unloaded, due to the uneven spring loads.
I understand Tiger Paw are producing a video to assist with fitting. It isn't clear to me if this will also show how to adjust the suspension and set-up.
