Jordan top sash guide

A quick learner from Texas says:
I have a Jordan window I need a top sash guide for. The current one is 5/8 with a top plate 7/8, top screw at 3/16 below plate, second screw at 1 in below plate, overall length 1 11/16 and the body is 5/8 by 5/8. Can you help me identify it?

Based on my measurements, for the balancers, I will need the S390-29. Some of the balancers I'm replacing have 2820 B.S.I, others have 2830F. Do I just ignore the B.S.I and the F and select 2820 or 2830 as appropriate? Thank you!

Could our 18-166 be a possible match for the top sash guide? As for the options, I would recommend the 2820 and 2830, yes.

Actually these do not work on my Jordan Windows... the top needs to be 7/8" by 5/8 or 17/32'
I installed two and when I tried to lower the spring parts on both sides would not catch, one did the other did not...

In that case, could you use our 18-044?
