Anyone have a part number for the tunk gas shock on a 2004 SIg 270? Seems like the trunk lid on my boat was damaged by the PO replaced and they put in the wrong shock as it fails to hold up the lid. Lid is too heavy. I replaced the shock before I knew about the damage so all I did was replace a non working shock with another non working shock. I can measure the length but need to know the weight LBS rating for this trunk shock.
