My update was to use flat washers ( used on nut and bolt hardware ) between the coils then run a string through them so you don't have a pile of washers flying everywhere when it comes time to remove them.

What you would do is bend the spring by hand, insert a washer leaving the hole exposed. Then bend the spring in the opposite direction and insert another washer. Keep doing this along the length of the spring until it is expanded enough to hook to the hinge. A triangular shaped pattern of washers would probably be more stable and keep the spring straight.

Insert a string through the holes, tie it off then close the hood slightly and the washers will now be free to escape.
