Figured out how to make new spring clips for the top. Look at the picture if you don't know what I'm refering to. Both of mine were broke and the thing rattles. Anyway, while trying to locate spring steel to make new ones, a friend mentioned tie down steel was similar. I located some strap from a local new home site (accross the street!) and tryed it out. Cut an inch and a half off and bend it with a hammer and a vice, both of them took me about 1/2 hour, fairly simple and they work! Also although the strap is not quite as heavy as the original it's close, but it is the perfect width. Just thought I would share a simple fix for an impossible to find part.
