Basically, it seems that the distance from the ears to the beginning of the spline on the 1257 is a bit long, meaning that without any shims anywhere, it is about touching the top deck on the linkage side.

If the lip of the servo adapters (K,H,F) was a little thinner, then things would work out.

I saw that the XII has a similar servo saver, but it appears from pics that the adapter it uses has a slightly thinner lip, not sure though as the pics from xray's site are not that clear.
