Since I couldn't find out what the Heritage looked like with the Tour Pak, the only option was to go for it and put it on.
I'm trying to put up a picture in case anyone else wants to see what the bike looks like now. She has also left the Firehouse Customs backrest on since without it there was no lower back support.
It's worked out real well. She says it's VERY comfortable and has about 16000miles on this season.
