Sry it's been a while since I started with any project stuff. Since its gonna be spring in a bit I figured I'd crack back open my project binder and get cracking. I was going to drill some holes to fabricate a custom roof rack for a kk sky slider. Here is a basic mockup


I was originally thinking of creating a hinge in the front to allow you to open the roof but that would mean you wouldn't be able to move the rack when it was full. I then redesigned it so it would lift up using gas springs (the same kind of deal that the rear glass uses only much tougher) I figured out that the basket should be able to hold about 80 lbs and therefore each gas spring will be able to lift 80 lbs + the weight of the basket which will be most likely about 40 lbs. ( a total of 120 lbs or 30 lbs a piece.) I first things first though. I need to get a set of rails from RL.
Here is the math for the gas springs
(They had to be calculated in newtons. I understand newtons don't exactly translate well to kilograms or lbs)

This is what the gas spring hinge will look like


Any input is appreciated. I've been tossing ideas around in my head all winter.
