See the hole underneath shaped like a trapezoid? Look down in there, see the bolt head? Take a dremel and cut a V shaped notch to gain access to the bolt. If you take your time you can make the cut look like it came from the factory like that. Did you get the updated sparky from Yosh yet? If not call and tell them you have a 1st gen pipe and your sparky fell apart, they'll hook ya up. Its a much better piece and is worth bugging them for.
