Toggles:
If you really want to make your friend happy, you may be able to show him something else he doesn't know.
On the Americana I used, there were removable panels in the upper oven's walls; you could put them (and the racks, if you didn't care about smooth and shiny) in the lower P*7 oven.
The guy that house was rented from had bought the range new, and he was stunned to learn from me that years of hand-cleaning the upper oven had been unnecessary.
That feature may vary from year to year, and/or model to model, but if your friend doesn't know about it, it'd be worth checking to see if his has it.
