Hello, Your balance shoe resembles the 15-087 housing pivot shown below, which would use the S180 coil springs, 15-086 tandem housing, and 16-024 or 16-031 mounting bracket. Take a look and compare the specifications below to yours. Detail of 15-087
Series 180 coil balance diagram
As for your tilt latches, review the dimensions of the 26-390 and 26-391 below compared to your original latches. Thank you! Alternate image for 26-390
