Rider Backrest for the Freewheeler

[MDO]

Does anyone know if the Grasshopper backrest will work with a mustang seat? I already have the grasshopper backrest and I am about to order a mustang seat. Of course I was wondering if I need to order their backrest as well?!

I'm not sure. I have the HD Tallboy Sundowner seat. I would think they make the slit in the seat to align with the bracket location. I don't know anyone who has the Mustang with a Grasshopper.
