And VW used the same style heat on their vehicles. Exhaust manifolds had
large finned aluminum blocks cast on them. With a sheet metal shroud
around it. They connected to sheet metal tubes formed in the body. When
NEW and sealed they worked OK, When they started to rust the heat
started to go away...

Of course I turned around and made a similar unit to heat one of my
first lawn tractor cabs. The factory round muffler and an accordion
formed aluminum heat exchanger. Used some sheet metal around it and a
small computer fan to move the air.
