I have a Glasstek Sunoco bolt hood on my 75 Camaro. The pass side hood spring stays up at the back when it's closed. I tried all kinds of adjustments and nothing has changed. I even slotted the holes a bit on the two bolts that move the hinge up and down. You have to push it down every time. It has the low tension springs on it. If I remove the spring the hood will sit down properly. Looking for some suggestions. Is it time to replace the hinges?
