I made a tool by flattening the end of a welding rod and sharpening the flat to fit behind the bottom clip from the top to get the bottom of the strut off. The struts are after market and have a sticker with 4453 printed on it. They are 13 1/8 inches between the ball holes extended and 8 1/2 to 8 3/8 inches between them compressed. I find a number of 13 inch gas struts on Amazon rated from 20 pounds to 65 pounds, so the remaining question is what was the rating of the original struts or what pound rating should I order to make sure the bonnet will not come down in the wind at car shows. The bonnet weighs 23 pounds at the rear edge when closed to 10 inches on a scale without struts and that edge is 45 inches from the strut ball studs so the struts would have to be stronger to help lift the bonnet at the front.
