Spring clips for sash style window

A home owner from New Hampshire says:
I'm looking for spring clips and springs for my home's sash windows. The house was built in 1985 and it has the original windows. Over time, the clips and springs have broken and the window no longer remains opens without support. I've attached a photo of the two different types of clip (left and right sides). My search is a long shot and any advice would be greatly appreciated. Chuck

This looks a lot like our 20-006 Crestline clutch set. See if you agree.
