This is excellent work by DMGRS. As recently as this summer, these adaptors were completely unobtainable.
It's worth emphasising that owners of a ZT180 Sports Auto will also need these adaptors. Laser Tools and Sealey are incorrect to say that the Rover tools should be used (if you try you won't be able to fit the rear belts
).
Further thanks are due to DMGRS for making the timing tools available for hire at a realistic price.
