>From what I see the brackets spot-welded to the upper rear of the battery
box are shaped so as to keep the seat from going much past vertical and not
hitting the battery box.  The brackets are soft, so don't flip the seat up
like I did....the entire seat broke free.  I said some bad words then
straightened the brackets and riveted them back on the box.  Inspect the
seat frame to be sure the metal is square....if the rear of the seat frame
is just a little bent, the seat (when raised) will hit the batterybox.

I have the pins and hinges and all - they are in good shape. When you hinge
the top open, it looks like it goes almost vertical before the rear lip on
the top hits the back outside of the battery box. On mine it wants to keep
going but things start getting bent - hence the crack. So what is supposed
to keep it from going too far? I'm thinking perhaps originally (with a good
lid) the top lip hitting the back is supposed to do it, but there that
doesn't look very substantial (which, of course is why they bend and 
break).
I just want to be sure I'm not missing a stay or something. If there isn't
anything else, I'll add something of my own.
