Pop Top Gas Struts Mac 25 by Timo42 90lb 24 struts marked gsny 230090, 3 in front of rear support on top, right angle mount, 5 behind lower pivot for front support, straight mount, I bought all the parts at W/M. Make sure the strut holds the top as high as it will go so you have to push it forward to get it down instead of just pushing it down, the struts dont interfere with the supports as you move it, and the top closes fully without bottoming out the strut.
