Deere 2320 - looking for a hay head

I am in the business of wildlife habitat establishment/enhancement, but also cut a little hay for my wife's horses, and the neighbor - only put up about 40 acres a couple times a year - have been using an older Hesston hydroswing to cut, but would prefer a self-propelled - found a decent Deere 2320, but it has a draper head on it - would like to find a 240 or 300a auger head for it - any ideas on where to find one?  Will a hay head off of a Deere hydroswing work?

 

Thanks!

Dave
