I need you help me to identify following parts name and item#

I'm afraid that I don't recognize the components you show in your photos. At the very least, I can tell you that these aren't parts that we sell. Would you happen to know who made the window? 

Thanks so much! Please give us just a little more time to look into this and I'll get back to you ASAP.

Thanks again for waiting! Please see our 67-012 sash ramp. This appears to match your original block, but look it over and let me know if you had any questions.

Dimensions for 67-012

Awesome, thank you! We really appreciate it. Best of luck on the project and please don't hesitate to reach out if we can offer any further assistance.
