Bubble weatherstripping for older alliance windows

Question

I have 40 rental properties with these windows and desperately need this weatherstripping.  The one edge has a pliable edge which you can see in pic 4.  I have tried a couple of samples from you but they will not stay in the track.  Please help.  Thanks.

I believe you have either our 58-171 or 58-182, depending on the size of the "T" that installs in the track. If your "T" differs in size from either of these, I need to know exactly how big it is so that we can find a better match.
