Purchased a 1974 1.8 this summer and absolutely love the car. But as the winter months approach here in Clovis CA, it gets a little cool, and I noticed that I wasn't getting much heat out of any of the vents. I wasn't to concerned about the matter at all until I noticed, going through a box that came with the car, that there was a part in the box that looked an awful lot like an heater blower assembly.

My Haynes manual is of no help, does anybody have any diagrams, schematics or pictures of how to install this thing into the engine compartment; any and all comments are appreciated.
Thanks,
Greg
