I plan on holding on to my Lincoln Mark VIII for a while, not the best family car but sometimes we need to use it for the kids. Ford still makes available, for free, tether anchor kits for car seat straps, my current Ford/Lincoln dealer ordered them for me. Before they were standard in cars Ford/Lincoln had them as an option in late 90s early 2000 cars that could be installed by a dealer at no charge. I got two outboard seating position kits, you can get a center kit too. Installation was easy and detailed instructions were provided. The hole in the rear deck back pan is there, you need to poke a hole through the carpet on the rear deck, it was strong and thick. If I was still particular I may have painted the exposed hardware with black Plasti Dip. The clip is chrome and the bolt dark gray. Photos of my install below.
