Replacement parts

Question

It is hard to see but on the 'a' picture on the right it has a '5' in there. I weighed the window and it is about 19#. There are two coils on each side so it looks like each side takes like 10#. The coils are .5 inches wide and 1 inch diameter. The whole thing when not broken to pieces is about 4 to 4.5 inches long and about 1.25 inches wide. It looks like the S140-11 or the S140-10 would work if it should be selected to be equal to the weight of the window but not sure if that is how it goes or each side is supposed to be at the weight of the window. The ones that were there have two coils and two screws though so I want ensure I order the right ones. I also need the top latches. Looks like they should be the 26-393B. Can you review and confirm? I am on a tight time schedule and need these asap.

I am afraid the Series 140 will not work here. This is what's left of a 15-180 Pivot Shoe, which uses Series 190 Coil Balances. The Coil Support will be the 15-186 or 15-181, along with the 15-182 Drum.

To know what spring weights to select, you need to go off stamp codes on the springs themselves. if there are none or you're uncertain, give me the exact weight of the window sash and I can work it out for you.

For the tilt latches, I suspect the 26-243 and 26-244 are closer. Compare the dimensions and see what you think.
