Thatnks for the offer but that's a little pricey to add to a $90 MAC muffler.  Besides, I don't know yet what I may or may not have to spend cash on to get mine running again.  I am considering going to a Sportster muffler at some time in the future anyway to quiet it down a bit.  I love the loud on the freeway but I leave early in the morning and I actually like most of my neighbors, so I'm considering quieting it a bit.  If I do that, I would have to reassess whether I need a baffle too.  Again, thanks for the offer and I may come back to you about it later and hope it's available.
