Iím designing the hinge to use 0.5Ē shoulder bolts.
Iím planning to use at least one gas strut on each side but will need to
figure out a weight estimate once I get a little bit further along. My goal is to take the fiberglass top to the local scrap metal yard and weigh it
Agreed, I was suggesting above that perhaps you could mount a very high force gas spring to each mech to help get some bias force to lift the roof in addition to the the other gas springs that you'll need. I expect you'll need some long travel struts near the front.
If you know anyone with free body diagram/static analysis skills you could do the calcs in excel; it would be a challenging but straightforward project. McMaster provides the start and end force for each strut so you will need the start and finish angles when the roof is fully down and fully up to make some plots. When you weigh the roof just assume the CG is in the center of the roof.
