The factory supplied the big aluminum plate. I made up the rest of it. Post a picture of your current setup if you can.

However all the bolts and rubber cushions were shot, and it seemed like a good time to do an upgrade. Here is how we redid it: Get a heavy duty muffler hangar kit from Advance or O'Reilly auto parts and use the rubber hangars. Now you can eliminate one of the original aluminum angles, you do need to weld a braced tab to the original bracket on the muffler. Also, I have never liked using the standard springs that hold the muffler to the header, so we converted to something less likely to break and go through the prop. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 Forgiving is tough.
