Daytona 1000 Timing Belt Tensioner Tool

Hi Folks,

Does anyone know who supplies the fork/socket tool used to torque up the tension on the Daytona’s timing belts or is there another option to adjust the tension other that wait till it snaps and then back off a turn.
Any info much appreciated.

I live in Lancs by the way if any kind sole has one I can borrow/copy.
