85 900 A/C Manual and Evaporator Drain

My Evaporator is leaking into the cabin. The drain is absolulety not blocked. Car is garage kept and I vacuumed the housing out when I rebuilt the system last year. Today I probed the drain, vacuumed it from the evaporator housing, blew it out with compressed air and ran a piece of weed eater line through it. Water drains freely from the drain tube AND trickles inside the car. I suspect an alarm installer may have drilled a hole or the nose of the evaporator housing is cracked. I wont get into it for a week or two but can you answer these questions:
No real info in Bentley. Was there a separate manual and can someone help me get it? Bentley lists dangerous pressures, etc but I have the training, equipment,etc. I want to see diagrams to guide me.
What is the nose of the evaporator like? I see where the drain tube attaches and bends through the fender into the outer wheel well. Does the tube slide over the nose? I am hoping I can disassemble it to epoxy a possible hole.
I have a parts car with a known good evaporator housing. What is involved in swapping it out? I think the answer is worse than a fan replacement although I have been through that previously.
Has anyone had a failure that resulted in leakage into the cabin? If so, what is the failure mode?
Thank you!
