I have been unable to identify these exact pieces or even very close to them. The do not tilt. I can send dimensions here in the next day or 2. I am looking into 3d printing but it will be more expensive I'm sure.

Hello,
I would recommend starting with our 18-060 and 18-061 top sash clips. See how the dimensions compare to yours to determine if one of these options could work for you. Thanks for posting!
