Spring function comes from the coil not from the leaf part of the spring. The coil on most of the broken springs was confined by the felt it was drawn up against. You can use a micrometer to determine which spring or springs were used. You can use replacement springs but you may have to drill another hole to draw the spring tail through to keep the coil in place. I do not suggest using the replacement springs because they are much too strong. This is the type of operation you can sit in front of the TV and do during an evening. Care must be taken to make sure the coil can open and close freely but be up near the notch cut for it in the rail. Look the situation over carefully, plan you work then work you plan. Lots of luck.
