Looking for a split high back bench seat for my 74 Duster Twister

Just picked up a 74 Duster Twister that someone put wrong (non) split front bench in. Would like to find a high back split bench if possible. Upholstery condition not important but prefer complete seat with tracks.
Also need dash area plastic parts & heater controls.
This car is Manual trans on the floor, manual disk brakes, & manual steering. Original Copper metallic paint & decals still on car...
Thanks
