My trick in close quarters is to consider wrenches expendable and use
a band saw to cut them down. Virtually all wrench handles are too

Buy a couple of sets of cheap wrenches from Harbor Freight
(US) or Princess Auto (Canada). Chop and heat and bend to suit special
applications like that fuel selector.
The 172's selector ain't really all that bad to get in and
out. Some are worse. The worst thing about it is the need to
completely defuel the tanks to do it. Some airplanes, before
manufacturers got cheap, had shutoff cocks at the tank outlets,
safety-wired open, and closeable for such maintenance as fuel valve
repairs.
