When I made the one it left a vent open on the other... I guess if I made the wiper notch bigger and really tried I could make them symmetrical as the difference seemed small.
Barnyard, I would love to take credit, but it seems to me I read someone else's post about this at some point in the past. Whoever they were, they deserve the credit.
They said it couldn't be done, so naturally I wanted to do it that way. On my 79 with factory air I changed the blower motor without messing with evaporator, heater core, etc. I don't know if it was really much quicker, but I could do one again in maybe an hour, hour and a half. And if it goes out again I'll be able to swap it in 30 minutes or so.
In a nutshell, I ground the rivets on the case under the hood, then surgically removed the motor, replaced, and sealed the case back with nuts and bolts. I took some pictures so I can give a more detailed write up, if anyone is interested.
The guide from NCS was helpful with the pics, and a guy here who had cut his case open also, I have to find his name.
NCS did say that if you remove the rivets you'll ruin your unit, but I'm not sure why, it seems to work fine.
I have a 75 f250, non air conditioning, and am happy that I don't have that big fan box in my engine compartment. I can R&R both my heater core and fan motor from inside the engine compartment.
I want to see a pic of how you can R&R the blower motor from the engine compartment. If you can, that is not the stock set up for sure. And it sounds like a cool modification. Normally you have to pull the heater box.
