Sash Cam Replacement

Looking for a pair of left and right sash cams.

Either need the exact pieces or ones that will work. Please see the enclosed photos and the dimensions below.

Length of the section with the screw hole: 15/16 in.

Width of section with screw hole: 5/16 in.

Thickness of section with screw hole: At the hole is 1/8 in.

At the sloped point is 1/4 in.

The top end that faces upward when mounted in the window sash is not a simple rectangle.

If the top end was a simple rectangle, it would be 5/8 x 1/2 in. But there's a cut-out of 1/8 x 5/16 in.

If you need any further information, please let me know. So far, I don't have the window manufacturer.

I just ordered two of your window balances, series 351 2830 for the same window. I'd like to avoid ordering custom made sash cams in order to save cost.

Again, looking for two sash cams, one left and one right.

Appreciate it.
