<VV> late model heater duct help

[judynrandy at comcast.net]

Hey all, 
I need some advice on how to EASILY remove the heater ducting from the '65 coupe I am working on.  Why, you may ask, do I have to remove it?  Simple.  Tonight, when dropping the tunnel covers I was greeted with a shower of MUDDY debris, twigs, dead grass, leaves, etc. It seems this car was in a bit of a flood at one point in its' life.  That would explain the different drive train and dead rear wheel bearings for starters.  Anyway, given this new info, my job now includes removing the heater ducting completely so I can wash all the mud and debris out of it all.  This has been lots of fun.  The blower is frozen solid.  There is "flood" kind of rust coming out of everywhere.  Strangely enough, the body is VERY solid.  Now I know why the front crossmember had mud caked up in the drain hole like crazy.  Also, since my job also included installing new brake lines and a wiring harness too, (the other one looks like an explosion in a mattress factory!  besides, who ever heard of taping bogus electrical connections with GREEN duct tape?)  and now replacing the clutch cable as the current one is really rusty up towards the front of the car and has numerous broken strands,  removing the heater duct sure would make those jobs a whole lot easier.  Not to mention now having to disassemble the pulleys and cleaning them and regreasing them.  And also having to check the operation of all the controls.  So, any pointers, helpful hints, or advice would be appreciated.  I've never had to do anything quite like this before.  Thanks a million in advance.
