Sorry for the lack of updates. It's not because I haven't been hard at work, it's because there hasn't been much visible progress.
Lots of fiddling around and a million details to take care of.....
Here are the results of "to-do" items that took far too long, "refinish engine tins" and "test fit muffler straps". Which turned into "shorten muffler straps"

This muffler better sound as good as it looks!
