Balance and pivot shoe replacement

I think we can help, yes. Let's start with the balances. I assume they are all spiral balances, as pictured? If so, I would recommend either our Series 600 (5/8" diameter tube) or Series 900 (3/8" diameter tube) spiral balances.

As for the tilt latch, I'm not sure what would best replace this. Can you give me its measurements? I specifically need its width and the distance between its installation holes.

Finally, we have your pivot shoes. You show two types in your pictures but you don't mention which set of dimensions correspond to which pictures. The first one resembles our 15-015, so see if that is a good match. I would need to see a clear photo the second one without the sash obscuring it.

Thank you! The pivot shoe on the left, with the blue cam, matches our 15-015. Finally, the shoe on the right could be our 15-046.
