Wow, my heater looks nothing like those...and I assumed it was OEM because it used the knock-outs on the passenger side of the body. Mine has a control flap that let's you direct the heat to either the passengers feet or over to the drivers. It's a square heating coil, maybe 8"x8" motor on top with a shroud covering it. I'd attach a pic, but the steps needed to attach a pic are maddening...
