Hi, I believe you have replacement parts for this old block and tackle balance. This is a single hung window, about 39" x 29" The metal clips at the bottom of the window are
2 1/2 " long. One has a 4 on it and one has a 5 on it.The rod unit is over all 27" long.
The black piece at the bottom of the rod is 1 1/8- or slightly under 1 1/4". I'm hoping you can help me with these parts and directions for installing them. Thank you so much.
Linda
