What many folks do with underseat batteries is mount the switch to the floorboard just ahead of the seat and between your legs so it's easily reached from the driver's position without having something underhood. Use it to break the ground cable. I've done this or had it done on perhaps a half-dozen 1941 Packards and believe it's the best approach. No bracket needed, just a hole in the floorboard.

Of course you could also use the switch to break the "hot" cable but there is a, granted remote, hazard with that should anything metallic like a wrench ever fall on the switch terminal an also touch the frame or body. Some who use the switch to cut the hot cable put it on the driver's side of the cowl, breaking the cable going to the starter motor. You'll need to very agile to reach under the dash each time you want to use the switch and, if it's location isn't very convenient, then there may be a tendency to not use it religiously - a habit you don't want to fall into.
