Compare your item with the one fitted to my car and others who have the uprated item that you have no idea about, you are assuming the linkage used is a std item like what you have. However it is very different where the knuckle joint is, THAT was the info that was not given out.... otherwsie how would you even know about this swap.!
The puma linkage swap was done about 6 years ago on my car for me and i still have the same one.
