Further inspection revealed a mouse nest in the fan area. Check this out...
Those are the desiccated remains of two baby mice

The evaporator core and case were removed easily and painlessly. The tip to remove PS front seat helped tremendously. Obviously I removed the offending mouse-debris and thoroughly cleamed out the core with compressed air. New O-rings were lubed with Mineral Oil, and I added .5 oz (or 14.79cc) of PAG oil to the new Receiver drier.
I did remove the DS headlight for easier access to Drier location, but that also facilitated another task —repainting the chrome trim around the lights. Reassembly was without drama. Evac’d the entire system and it held a vacuum.
Our Harbor Freight pump couldn’t quite achieve the recommenced -29Hg but the RobinAir gauges showed -25Hg. Recharged the system with 3 cans (36oz) of R-134a. The AC system did its thing, and once everything stabilized, the HP line showed 190psi and LP line showed 35psi, (while running) with cabin air temp of 39 degrees. I’m thrilled with that!
Again, my sincere thanks to all who contributed to the collective knowledge of this thread. Without it I would have taken my 80 to an AC specialist, and would be significantly poorer now
