Thank you for posting, and for the great pictures. Check out our 15-140 pivot shoe and carefully compare it to your own hardware. Does it look like a match to you? If so, then yo may want to check out our Series 150 coil spring. You may also be interested in our 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel.
