I purchased new hinges and springs from GM parts direct a couple years ago and specificly ordered SS springs. I've got the body back together with the new parts . After opening the hood fully it falls back down 3-4'' and I haven't installed the insulation or the louvers yet. The springs have 28 coils which i believe is correct for the SS hood. I don't think it's the norm, shouldn't the hood stay open fully? thanks Paul
