Replacement Window Weatherstripping

A home owner from Milford, OH says:
I need to replace the weatherstripping on vinyl/aluminum windows manufactered in 1998 with no manufacturer identified other than the code 3MI974 stamped on the inside frame of the double pane glass frame. The weatherstripping is an offset t-slot foam filled bulb type similar to product code 58-171 in your catelogue but the dimensions are slighty different and ther is no strip on the side of the bulb. The t-slot is 3/16" on the insert side and 7/16" on th exposed side. The bulb is 5/16". Any match or suggestions would be appreciated.

Can you submit a couple profile photos of your foam seal so we can take a look?

Hopefully the attached are clear enough to give you an idea of what I am looking for. It does seem very similar to product 58-171 with the foam tubing mounted along the outside edge of the mounting strip.

The 58-171 Foam-Filled Weatherseal is definitely the closest match online. The key measurement is the diameter of the foam seal, measuring .300" (which is between 19/64" and 5/16").
