I'm putting together a 2006 Mazda 5 for a project, and I've come across a mystery bolt. It's a hardened grade 8 hex head bolt, approximately 5" long, with a 16mm head. I've checked around, asked around, and dug around in the engine, but can't seem to find what the bolt goes to. Please tell me that it found its way into my garage from another vehicle, because I'm at a loss.
