Good luck and let me know how it goes.

Hello Walshie! Great advice--thank you. Got all dismantled Friday evening and Saturday, and confirmed the leak points with some focused tests. I found your forum conversation with Meir from 2016, and the culprit is just where you found as you described to him. Waiting now for the Wurth Bond & Seal to arrive, so spending time cleaning under the dash and re-taping all the wiring harnesses. Also repairing the interior of the heater box, cleaning the evaporator and re-foaming (or taping up with aluminum tape--not sure which way to go yet) the flaps. By the way, were you able to track down the part# of the foam gasket between the heater box and the bulkhead--the one that goes around the evaporator tubes as they pass through the bulkhead to the expansion valve? One of the previous owners tried to fix the leak by putting a bunch of sealant around the tubes (maybe it was leaking there as well--that lower screw is rusted just like yours was), and I would like to replace that gasket. Unfortunately no part number on the gasket and none of my searches yield anything...
I spent considerable time trying to clean out the small crevice right below the expansion valve. Tons of gunk in there and it was like flossing teeth because the car body at the base of the right strut mount (LHD car) has an outcropping just forward of the bulkhead plate that obscures visibility to the joint of the plate with the body. Also creates a channel where water accumulates thus causing this whole leak problem. Ended up using toothpicks and the end of a zip tie to get in there to scoop the gunk out, then flushed with water, and then dried with a heat gun and compressed air. It should be ready for the seal.
Anything else you did or parts that you replaced in the process that I should pay attention to? Once again, thank you SO much for your experienced guidance!
Best, Scott
