Hello there!

Your pivot shoe looks like a match for our 15-087 which uses the Series 180 coil springs, 15-086 housing and 16-031 mounting bracket. Since your housing is marked with a "6" and "7", you'll need our S180-6 6 pound and S180-7 7 pound coil springs. Look these parts over and let me know if you have any questions.
