Years ago when I had a normal opening harwood hood, I completely removed the factoryspring mechanism & added gas shock 10mm pivots to front of hood hinge. I think some later g-body's like regals came with shocks. Sorry I never kept my shock #'s or took pics, but it's not a big fabrication project.I hand picked a pr of shocks from an auto parts store by compressing & judging strength & length (approx 10 to 12" overall??) . Made lower mounts to attach to fenderwells with a few extra holes for adjustment. You can do a little simple figuring for location by putting tape on sides of hood near hinge & figure shock lenth open & compressed & how high you want to open hood & mark your locations. Besides stronger or weaker shock choices, remember that closer to hinge pivot means more movement but less strength & vice versa.
This isn't that hard with a little figuring & shock studs are available separately, got some from napa recently. Trust me this is very simple compared to my latest hood hinge mechanism.
