Curt does not specify which vehicle models require drilling or temporarily lowering the exhaust when installing hitch # C12211. It would appear that the 2000 Volvo XC70 does not require lowering the muffler but no work on drilling. I assume on some 1998 models drilling is not required.

I wouldn't recommend grounding your 7-way to the gas tank strap. Due to safety issues, I would stay as far away from the gas tank as possible.
