I have an electric penthouse top, so i'm not in the market - but thats a cool concept. I'm assuming you have a manual top and your interest lies in a simple solution to assist in raising your top? If you decide to implement these it would be interesting to follow the application & your thoughts afterwards. Keep us posted.
Edit: Wasnt able to uncover weight limitations on these - have you already inquired?
pretty cool. would be a nice backup plan for a failed electric top, but theres no listing or weight ratings anywhere.
