Hi,
I'm considering getting a South Sport trailer for my '85 911 Carrera, and I would like to understand how the South Sport hitch for the 911 works. Unfortunately, South Sport does not provide instructions for the installation. If you have installed one, can you respond and explain?

Where exactly does the hitch attach to the frame? Does it attach to the bumper (probably not)? Do holes need to be drilled in the frame, and if so where? Can you provide a diagram? Any help would be greatly appreciated!
