top sash guide for danvid window

Thanks for posting. Please see our 18-034 top sash guide and compare our measurements to yours. This could be a possible match, but you might need to file down the curve on the top of the guide so that the balance tube will clear.

I'm sorry to hear it won't work. However, we have not been able to find anything closer. Can you go into exactly why the 18-034 won't work? Is it a matter of size? If so, which dimensions specifically differ? We will need your exact measurements.
