For ’71 Duster – center console floor mounting brackets; floor shifter assembly and/or complete shifter linkage between shifter and transmission

Looking for a used set of center console floor mounting brackets - the long "M" bracket, the shifter bracket and the "U" bracket - see all three brackets on floor hump in the attached photo. Not paying crazy reproduction price. I'm checking the parts and parts cars forums here on FABO.
See also shifter and linkage photo.
Thanks FABO.
