simple tip for you Hush,
sorry for the hijack
you know those little nuts that keep falling out and are hard to get in the right spot for the bolt,
get a small length of plastic tubing cut it the horizontal length of the post and squeeze it in with the nut uppermost.
then put your bolts in - never lose your nuts again...
and get a spray can of battery terminal protector - never see those fuzzy bits again..
