If you can find one, great. Not common by any means. I used to
have an AM ground-switchable radio in my first Sprite.

Too dangerous: if something touches, poof. Switch the ground of
the car. The procedure is fairly straightforward except for switching the
tach (if it's not one of the early mechanical tach cars). Even the tach
only requires cutting and reversing the wires to the loop, if I remember
correctly. You also have to reverse the coil connections, the fan
connections I think, and repolarize the generator.
