Great diagram and pictures.
There are thread discussions on correct assembly and placement of the clamp.
I get more out of the discussions than I do from the negative feed back.
And I have found that a small ball pean hammer helps to tap the properly assembled clamp so it seats. And i try to use a floor jack to hold the muffler in place. Frees up my hands so I can fumble with the clamp bolts. The replacement mufflers I find at the swap have needed reworking the flange with said ball pean hammer to get a better fit.
