I've got a complete 60D Powerflow setup that you're looking for. Used it a couple of seasons on my 2305 w. 60D deck before I sold-off the rig and upgraded. I have the Powerflow blower, deck bracket, attaching rod, belt, drive pulley, all hardware and installation manual. PM me if interested and we can probably get you going.
Additional photos are attached as requested. I've been using Powerflow units for years and the bottom of the fan housings are susceptible to damage and / or wear. Added a UHMW poly wear strip to the underside of the blower housing. It's visible in one of the photos. I also have the brackets, drive pulley, all of the attaching hardware and installation & operator's manual to go with it.
