Do you know if I have to have the AC evacuated when we change out the motor? My ac works and it would be $78 a pound for new r12 + $80 labor (3lbs?)
Can the a/c compresor just be unbolted and the motor put in place then rebolted without r&r the r12?
Is there room to do this in the 79 300SD?
I need to do this today if it has to be done...

(just the evac)
