Hard Top Window Struts

Are the hard top window struts re-buildable or just disposable? Where can I pick up new ones and/or parts?

Thanks!

they are not rebuilable but pretty inexpensive from jeep part number 55076310AD $36.00 ea some auto parts stores carry them around the same price maybe a few bucks less

Thanks for the part number, Nick! Probably easier and cheaper in the long run picking them up from the dealer than spending time trying to track them down in parts store.
