Replacing blower motor

[Isensee@aol.com]

I am going to replace the AC blower motor in my Bricklin. From the pictures  
in the parts manual, it looks like I can just remove the nuts that attach the  
blower to the firewall and pull out the blower motor and fan into the engine  
compartment. Can anyone tell me if that is right or do I need to take apart 
the  air box inside the car?
