Ry,

You don't want to even try (IMO) to pull the condenser without dropping
the radiator.  Too easy to screw up one or both.  If you've already
ordered a replacement condenser, might be too late, but you'd be miles
ahead if you replaced the stock condenser with a newer cross-flow
style.  The stock condensers are really inadequate for use with 134-A if
you live anywhere hot (like here in Phoenix AZ).  You can get conversion
fittings/hoses and a new condenser for about the price of a new OEM unit.

One thing you really do need to do, although a pain, is pull the A/C
compressor and drain it to make sure all the mineral oil is gone.  Then
you can put the correct amount of oil (PAG/POE) in the system before
recharging.
