I'm not actually going to mount a hitch, but I need to know what they fasten to under the car, specifically on my 2002 Focus. My guess is that you drill holes in the frame to match a hole pattern on the mounting pieces that come in a hitch package. I won't be buying a hitch so I won't know how they do it, or what are the best places to drill holes. I want to bolt members underneath the car on both front and back that I can slip a bar or pipe into that I can use as tie-down points. These will be points for tying ropes coming down from a roof rack. I don't want to go drilling holes and later find out there was a much better place to do it. I will appreciate your suggestions. Maybe someone can refer me to a diagram on the internet.
Thanks. Bill S.
