[V8] Radiator removal, and other ????'s

[jpb3]

Ok, This PS TB cover is a real PITA!!!!!
I have removed every 12mm bolt, the generator, the 13mm bolt and the small
hex head bolt at the top.  Do any of you remember having an 8 or 9mm hex
head bolt below the serpentine belt tensioner??  I have one that is now
rounded off.  It is right below the 12mm semi hidden bolt you remove that is
hidden under the tensioner.  This "Hex bolt" I am having trouble with is
also only accessible by rotating the tensioner.  This leads me to the
subject line....

I have the front bumper off the car and want some advice on removing the
radiator.  Do I need to disconnect the trans oil lines and the AC condenser?
My Trans lines coming into the bottom of the radiator look very, corroded
and brittle.  I do not want to touch them if at all possible.  I need to
pull the radiator to get a better look at this bolt that I need to somehow
remove.

This is the first time I have done a TB job on a V8, so far it has not been
very fun!!!  I also have the cam locking plates, can anyone give a brief
synapses of why they have two sets of holes on each side?  Shouldn't you
only be able to lock the cams in place in one position?  Thanks for any
help.
