Well, I fianally got my Doka back from the AC guy and the install looks great!  The set up is under the rear seat and the condensor is under the left side of the truck with a blower; not visible when you look at it from the side.

The cooling, significant.  If I don't sound excited, that's because I'm not yet.  It blows cold, but the difficulty is getting the cold air to circulate all around the cab.

What I need, (and this is my question), is a 12V in-line blower to boost the circulation of the evaporator unit.

Didn't the 2 litre engines from the earlier years come with a blower mounted in the engine compartment?  Was it an inline?

Does anyone know of another inline 12V blower that is small but "mighty"?

Part of the problem is getting more air under the seat by adding a vent on the sides of the seat base.  It works better when the rear seat base is out. But it definitely needs more circulation as well.
