THANK YOU ALL ! 
.
I appreciate the various interconnected links .
My hands I think are too big to fit inside .
I have zero plans to take the dashboard apart , I'm an old Man now and crippled to boot .
The Evaporator box drain tube is easily visible from the passenger side foot well and is fine ~ I ran my garden hose in and it didn't drip one drop on the inside of the car (whew) .
I guess i'll have to go look for the stuff with the hose to get it in there ~ I tried spraying some purple cleaning stuff in there but have no idea how much of the Evaporator it actually touched , my Cheap Harbor Freight inspection camera works fine but looks in at an angle , not directly down across the fins .
I _can_ see the Evaporator is black unlike the one in my TD , it's the same year car but is still aluminum colored .
i have the front of the car apart for new Condenser and SANDEN compressor so it'll be a while before I get back to this cleaning .
I installed the new URO brand blower motor , it works fine but is somewhat noisier than the old original one .
I need to figure out how to open the center vent flap , I did it a few years ago but it's closed again and I'm betting the vacuum element is bad from old age now .
Again :
THANX FOR ALL THE HELP & REPLIES !
Remember : I will
NOT be taking the dashboard apart

That's Young man's work , I am not young & flexible any more
