Stewart Warner had a model that fit under the dash by the glove box. It was
an easy installation. I found one in a 67 bus and put it in my 70 westy. I
had it gone thru and the seals replaced 6 years ago. it was still working
great when I sold the westy last year. Easy to use, lots of heat, just
right for warming your feet up on a cold winter morning. I miss having my
windows defrosting long before my engine warms up.
