I just about hit the floor when the parts guy told me the price and added it was sold as a complete unit only /forums/images/graemlins/mad.gif. I bent the link backing up my wood ramp. I ended up bringing it to a machine shop and they put it in a press and bent it back
( $10). Binds a bit but better then spending $$.
Sweet was is the closed and max open lengths for the link you have?
