Just thought I would follow-up. For those attempting this job, you need a Triple-Square bit, 8MM. It is very hard to get the bit in the fastener, I had to hammer it in. Getting the pins out at the other end is a bit of a pain, I used an old chisel and hammer. It would be better if you only do one side at a time, that way you at least have one worn strut helping lift the hatch. Also might help if you have a willing helper available (wife was not happy!)
