Mike,
Scott has extra wood for sale. Maybe a fireproof floor pan on the passenger side and you would be in business.
On the serious side, I don't know where your heater radiator is located but the ones in my cars are on the inside and behind the darn duct work and a ***** to get to. I had to change one a year or so ago as it was leaking and the water and anti freeze was showing up on the floor mat. And my cars are older, but I did have the loop from the pull knob slip off one of the flap openers once that directed the blower air from the defroster tom the heating ducts. Good luck.
Ron
