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"!!

Plan on removal time tripled for installation.

On my 230, one of the heater core mounting brackets had broken off.
Once soldered back on, there was a gap between the heater core and the mounting gap in the cabin.
I used rubber faucet washers (one on each side) to fill the gap and used nyloc nuts on the securing bolts. They were tightened just snug, not to create any stress on the heater core brackets.

Joe, I sort of figured those kind of numbers. Fortunately we not under any kind of rush.
Naj, excellent comment, thanks for the insight, we were a bit concerned about the fitment once the bracket was repaired.

I notice that you still have the fresh air cowl in place. I found that re-connecting the levers was a lot easier if you unfasten the cable to the fresh air flap. Then you can move the control unit around (some).

Then by taking out the fresh air cowl, we can manipulate thigns a bit easier? And get some extra hands room?

It's more like you don't have to fight the tension on the fresh air cable when reconnecting the cables to the control unit.
And it will give you a chance to check out the fresh air filter and the flap gasket! To say nothing of the correct routing of the windshield washer hose.
