124 evaporator quick question

[locry]

i'm tackling the dreaded 124 evaporator job. i've managed to remove the dash and everything in the way... took me around 4 hours... i'm getting ready to remove the heater box, my question is: will the part where the blower motor is come with the heater box? is it one big piece? or will the section outside the firewall(where the blower is) remain where it is?

one other thing, it says in the DIY section that i have to move aside the ignition switch, how do i do that? i didn't have to remove the steering wheel when i took off the dash, can i move the ignition switch without unfastening the steering column? i haven't had a good look at that section yet.

thanks guys!
