QA1 install.

My first experience with a qa1 k as a prototype was it did not use conical washers like the factory one. Are the production units different? My second concern is the strength of the cantilevered attachment for the strut rod. Otherwise, Id like to hear from people who have done direct swaps where the k was the only change.
Did everything fit exactly as before?
As a contributor of the front end chassis stiffness, this can be beneficial swap if it is significantly stiffer than the original.
