does anyone know if you can put pipes (duals) from a heritage to a duece. are the swingarms the same (bolt patterns) and are the frames the same

 

After changing out the pipes on my Deuce, I imagine that the swingarms are all the same. I wouldn't think that the MoCo would go to the length of drilling different holes for each softail model.

Check out the right side of the swingarm. Mine had drilled/tapped holes located there that were plugged, which leads me to think the MoCo used them for other exhaust applications.
