replace balance coil/shoe, etc.

A quick learner from San Francisco says:
By the looks of the pics I submitted, I believe I need (2) 15-087, (2) S180-5. Am I suppose to have 15-086 installed as well together with 15-087, or is 15-087 is all that I need to replace if I did not see the 15-086 when I took the sash out.

Also, do you guys sell vinyl covers too as I had to cut out an opening at the top when taking out the balance system, and the hole is larger then my original cover.

Thanks for posting. I agree with the parts you picked out. The 15-086 is meant to be used when you are using more than one coil spring on each side of the window.

At this time, we don't have vinyl balance covers. I apologize for the inconvenience.
