Re: Xf C4 Selector setup
Most people would use an aftermarket shifter such as a B&M megashifter or B&M quicksilver. They run a cable so it avoids the issues your having.
If you want to run the linkage? You'll have to knock the tunnel back. Just beware under hard load or twist is causes the box to change gears. That issue cost me $2500 in cyl head repair.
