Here is the problem I see with that heater. That won't fit behind the dash. Therefore, you will need to put the blower section in the engine compartment through the firewall. If you do that, it will be pulling its air from the smelly engine area. Further, you won't be able to shut off that air flow, even when the blower is turned off. Suggest you get the Vintage Compact one from Tristates. Easy to install, recycles the air inside the passenger compartment. Install is easy.
