Ryan ,

Is it a Motorsport shell do you know or a roadcar shell , may explain the lack of ABS loom hole ! Page 13 of "How to prepare the Sierra for Motorsport " has an identical pic to the one youve posted , with one big hole and not several , like Steve Broadmoors white Roadcar 3dr in the bottom pic . No point looking at mine , i re-drilled loads of holes and welded up several too !
Regards
Tony
