Best source for window felt

[Malamute]

I've searched and it looks like there are a few options. I was thinking of GMC Paul's but if there is something better I'll take it.

I tried to adjust the originals which had slid down the doors and they are so old that the window just keeps getting caught up. If I'm going to replace the felts what about the sweeps at the same time?

The felt in the wing divider is fine so I won't be replacing those. My plan is to pull the door panels and lube up the regulators at the same time.
