Ya mine got stripped by a gust of wind as well. Got replacement from my dealer, they had them in their store. I looked around at car parts stores and could not find a match for it. Have to make sure you don't go with one that is at a higher compression rating, makes it too hard to close the door then. Did not keep the packaging so can't tell you who makes them. Had the rig in at the dealers at the time and took the old one off and had it in my hand when i was looking for the replacement in the store to make sure i had a proper match. The one under the dinette table has gone now as well, but i am using a bungee cord instead and it works better than the strut ever did.
