I have an A65 in a T Craft I'm refurbishing. (sorry not a bipe) Exhaust system is rough. I have a pair of Hanlon Wilson mufflers off my Dad's 65 Champ, I've been saving since I was 10, when the plane was wrecked in a storm. Dad pulled them off before the insurance took the wreck. Unfortunately he didn't get the elbow stubs to connect them to the engine. I'm looking for 4 stub elbow pipes and one of the clamps. Anyone have some, or know who I should contact?
