This thread has me thinking. There is a big space up front
on air cooled Vanagons. Would you be able to fit a BA6 up
there?

I will have BEHR front AC shortly and the evaporator will be
behind the front grille, so it will have to cohabitate with
the BA4.

Any thoughts?

here is what I have done on my 78 when I got it there was a
non functioning A/C and a fully rusted out heat system. So I
removed most of the A/C system, put a BA-4 (from a 412)
under the front of the bus on the evaporator brackets,
reconfigured the A/C blower system to draw air from under
the dash and duct it to the under bus heater. The output
from the heater was ducted back into the stock heater duct
just behind the front beam. The entire stock heat system
from the front beam back has been totally removed.

I get good heat and plenty of airflow....
