Glad to hear everything worked for you so far! As for this hardware, the pivot shoe and coil spring you show have actually been discontinued by the manufacturer. They recommend the 15-158 pivot shoe with a Series 152 coil spring as a replacement. Other parts you might need, if broken or missing, are our 15-143, 15-144, 15-145 or 33-072.
