Top sash guides 18-166 and Series 390 balances

I have tried numerous times to add this to th discussion,77-58520 but it keeps telling me
"an error occured with your submission"

I am on my second repair job using the parts I have purchased from you and I noticed a big difference in my top sash guides and the ones I purchased from you. I was not expecting them to be exact and they will work, but I was hoping we could get a little bit closer to the originals. I purchased your #18-166 guides and 390 channel balances. My concern is where the sash guide makes contact with the balance. My originals had a much larger "hold" than the new ones(see pics). I would greatly appreciate if you could possibly see if you have something a little bit closer to my originals as the new ones barely make contact.
Thank You so much for your help! You guys are great and I appreciate your great customer service!

This is a little weird. Can you give me more specific measurements? Look at our 18-166 for reference. I would like each measurement for your top sash guide as we show for the 18-166. Thanks!

Sorry for the delay in responding. Here is a pic of the measurements of my original Sash Guides. Sorry for the crude drawing but I am not much of an artist. I measured this with a cheap Harbor Freight micrometer and many of the measurements came out to 64ths so I converted them to the nearest 1/8th as these are well over 30 years old. The guide on the far left is one of you 18-166s and the one next to it is one of my originals.

Thanks again for all your help and great customer service!

Thank you for your patience in this matter. Unfortunately, after extensive research, we have been unable to find this exact top sash guide, but our 18-064 may be a possible match. What do you think? This is used in many Jordan windows.
