Exhaust pipe stay

70-6978 is an exhaust pipe stay, a small bracket that holds the exhaust pipe steady against the frame so it doesn't flap around and crack at the header or work its clamps loose. It shows up in the parts book figures for exhaust pipes and mufflers on the TR6C, as well as a U.S.A.-market exhaust pipes and mufflers figure, and in a combined figure that also covers folding footrests on the TR6C, so it's a piece that lives right where the pipe meets the frame or footrest mount on that machine. Catalog appearances for this number run from 1967 to 1971. It also appears under the earlier E6978 form for anyone working from an older parts book.
