Andrew, I want to replace my worn-out Tasman MK2 with a new yale quattro which is a drop in replacement for the Tasman MK3 and MK2. The problem is that the MK2 3point lock kit is not compatible with the yale quattro because the center lug on the (plastic) 3-point adapter is too thick to mate with the socket on the back of the yale quattro. Do you know if the adapter for the yale quattro is available as a separate part that can be bought and fitted into a MK2 3point lock kit ? That would allow the MK2 3point lock kit to work with a MK3 or yale quattro lock. Thanks for your video, which is a good overview of this lock system. You show lots of detail which is important. Cheers, George.
