A quick learner from Ohio says:
I need to replace two types. One has the number 10 on the coil. The other has 7K. Both springs 1/2 inch wide

Hello! Your pivot shoe looks like a match for our 15-177, which is designed to be compatible with our Series 152 coil spring. The only issue is that we don't have a 10 pound option for this Series. With that in mind, I would suggest using two 5 pound springs on each side.
