Review on 💪 Premium Gas Prop Struts Shocks, 20 inch 67 LB - 2 Pcs Set with Mounting Brackets - Perfect for TV Cabinet, Trap Door, Floor Hatch, Toolbox, RV Bed - Lift-Support Gas Springs (20" 300N) – Supports Lid Weights 35-50lbs by Phillip Brown

I needed new spacers for my truck's rear window cover, they fit perfectly in a straight line and much better than what I had. I was wary of mounting them on glass because I didn't know how much they would shrink. So I installed them anyway, like any good pet installer would. And they were the perfect length and stiffness for my tight top cap. For those who don't know, there is a difference between a truck cover and a truck cover. The lid is a rigid trunk lid. The truck cap is an RV/tank. For those who need a lid shock I don't think this is what you are looking for. I don't have it, so there's no way to check.
