When I got my Sidekick way back in '89, the back seat was a $850
installed option,

I was told that they were shipped over here as
trucks, instead of cars, because technically without the back seat, that's
how they were classified. In Japanese, trucks are called a Yoe, and on
the rear diff, I saw a painted name, it said "YOE A" I think it was an
identification of the diff, truck-automatic which was the type of trans I had
I'm not sure why I posted this, just something that came to mind, and
I thought might be of some interest, and might be a lost tidbit of Zukilore
if not put into print.
Enjoy,
