for the glass hatch? It's a bitch and will cost over a $100 in labor not incl the two glass shocks which are around $35 ea from bma.
however, there is a write up somewhere (maybe bruno? or gale?) on the procedure, but the key is a long flat head screwdriver, or better yet one of those forked weed pullers to force that little compression fit end on the shock that needs to snap onto a ball mount deep inside the roof.
