AC/Heater Blower motor

[Hunter]

Ok I repaired my AC/Heater box this weekend under the hood, as it had a hole in it the size of your fist from someone that did not know how to repair the AC. It is all repaired with fiberglass. I forgot the position of how the fan motor was located on the housing. Does anyone have a picture of a 77 blower motor mounted to the housing? It has one flat spot on one side the rest is basicly round.
Thanks Steve
