Sorry, whenever I hear about removing the receiver dryer I have to laugh, 
cause its easier than crying,
There is no way that I can remove the receiver dryer from my car, without 
cutting out the existing one. The evaporator compression nut has corroded 
to the extent that any attempt at loosening the nut result is distortion of 
the evaporator copper tubing. Ive tried PB blaster and other penetrants to 
no avail. Tapping it with a hammer also had no effect,

The corollary is that Chris Miller had no problem in removing the receiver 
dryer from his car..
.I have his evaporator now, so cutting out the receiver dryer in my car is 
an option (if i damage the evaporator, I have a backup)
