Attached is a photo showing Barry getting one of the heater levers unhooked in our quest to remove the heater core for repair. He is tall enough to look over the top of the windshield and still have his hand on the wrench to loosen the small crown nut on the lever. Second photo is the two of us, with the offending unit in plain site in the light of day.
We were successful in the removal process, following the information on the wiki and using the BBB. We are planning to note any differences or difficulties to add our experience to the knowledge base. It was mostly straightforward, but still a pain in the butt and back.
Two people that can work with each other made the process go fairly smoothly, once one or the other of us was in position to get at a screw/bolt etc. and discovered that we had the wrong size wrench, the other could respond, and where we two wrenches were required, we could work it together.
All told for today, it was a little less than three hours and we had the core in hand. Note this is after we had already gotten out the glove box, clock, radio, instruments and main plenum.
I am thinking we are probably going to need a few more than three hours to do "assembly is the reverse of removal"!!
