The joint on the inlet to the muffler is an automobile ball joint from the muffler shop.  I went to the auto parts store to get the springs used on the bolts clamping the ball joint together.  This is heavier than the normal aircraft ball joint but was available and inexpensive.

Dennis, just one question, it appears that the muffler is solid mounted to the engine mount without a swivel joint onto the manifold.  JohnD
