Hey guys, I have a 1971 fiberglass formula hood I have transplanted on my car (you may have seen posts on my Frankenbird), and I originally purchased light weight hood springs because of the fiberglass. Well, that hood is I bet almost as heavy as a steel hood, so needless to say, they give NO support. Do I use orginal springs from a steel hood? I have plenty of them from other birds. Or is there a spring that is heavier than the light weight, but lighter than the original stock springs?
Thanks!

Got Poncho?

From what I can remember use the regular ( steel hood) springs if it's a stock GM Formula hood. Aftermarket (like VFN) Formula hood uses light weight springs.

Make sure your factory Formula hood has the added steel stiffeners that Pontiac added after realizing they were needed due to hoods snapping in half when closed as a result of non-lubed or worn hinge assemblies.

Bowties are for Pee-wee Herman. "Chevy": even the name sounds cheap, but not as cheap as your Pontiac will be with an LS transplant.

Thanks Phil- That's what I thought. It is OEM with the steel bracing
