Top Sash Guide

A quick learner from Irvine says:
Hi there,

I'm trying to find a place to buy this top sash guide, but I don't have a part number, and John Evans' Sons won't get back to me. Do you have any way to help me purchase this? I've included photos of the piece, as well as photos of the top sash guide installed and where I've taken it off. I need at least 2 of these; best would be to have 4 of them.

Thank you!

Just want to add - I've identified this part as a piece used in the John Evans' Sons SideLoad Constant Force spring system. I can find the other parts of the spring system here (and ordered them last week), but I can't find this darn top sash guide. My window project is so close to being finished but for this piece. Please help if you can! I just need to purchase these top sash guides, but I don't know who sells them. Thank you in advance!
