I have a 2005 V6 Convertible. Today the top wouldn't go back up. After monkeying around with it I found a metal arm, about 12-15" in length that was broke. There's a similar arm on either side of the top. It's job appears to be to straighten up the top about half way thru the travel. It connects to a metal arm on either end. I was able to get the top up with a little manual assist. Every foot or so of travel I grabbed the hard shell front part of the top and straightened it up so eventually it would lay flat and the two main arms that form the edge the windows fit into snapped flat. My question is can this single arm be replaced?

 

Not sure as I dont and would not own a vert for just this reason.
