Here is a link to some pictures for a fan replacement. It was difficult to
find a fan that low profile, large diameter, easily mountable. I am working
on putting this together as a kit. I would recommend that some type of heat
insulation be installed on the firewall and floor area. This fan boasts
2,500 cfm at 17 amps. This the same current draw as the smaller fans used
without AC or the earlier vans. Using the low speed resister of the later
vans with AC the current draw is 12 amps and the medium speed brings it up
to about 15. If you have the late/larger fan set up wiring is direct. Use
what you have.

As a kit I am thinking around $220 for the later vans, $260 for the ones
that will need a resistor and harness.

What do you folks think?
