Mopowers' 66 Dart Build

i havent done the trunk on my 66 yet but i did on my 40 dodge,,the factory truck prop on the 66 cuda is a spring in a tube,,kinda like an early shock the factory trunk hinges on a early cuda are fragile,ive seen a shock that is not charged by gas,,it holds the lid up some how with no resistance,,the guy told me he seen it advertised in a mopar magazine,, but ive looke every place,, they just started using them at work to hold up tool box lids,,,i am going to find out hwere they got them at,,
