I made two tabs to hold stainless clamps to the outside of the left baffle (photo 1). I don't have a second clamp, and I ran out of CCP-42 rivets! so I didn't go further.
The tab in the photos ended up being mounted too high. The upper, angled barb touched the upper cowl when I test fit it. Damn!
So I drilled out the rivets and lowered the clamp by about 1.5".
