A little simple geometry & physics here.
The closer to the hinge pivot point you are results in more travel and less shock strength. IE, closer requires stronger shock
The further from the hinge pivot you are results in less travel and more shock strength. IE, further requires weaker shock.
Shock fully open sets your max hood opening, but shock does not need to be fully compressed when closed. You must have a little freeplay with shock travel not bottoming out when fully closed, resulting in hood binding & eventually damage. Plenty of ways to inspect shock travel with hood closed, including the modern cell phone video method.
Longer travel weaker shocks mounted more forwards put less stress on mounts vs shorter stronger shocks mounted closer to hinge, though both versions could have similar result.
These parameters can give a little adjustability when making a non adjustable shock work.
No rocket science here, but it is shocking how many people don't understand the basics, pun intended.🤔 I install commercial door hydraulic closers at work, which most all have adjustable spring pressure & closing speeds, which have to be set according to mounting location of between 90 to 180 degrees of opening range. Too bad surface mount closers are so heavy & too bulky for automotive application.
Gas shocks can also be substituted with electric linear actors, but damn these things are slow to me. Some lowrider guys with air ride use air cylinders, which usually give a fast, but harsh movement.
RV and truck topper supply stores are also a source of universal shocks (listed by length & strength), as well as some marine sources.
Just some food for thought from the guy with the most complicated hood mechanism.
