Help me fix my wobbly windows!

Alright so now that the Duster has been back on the road the past few months it's time to tackle this problem once and for all. I met a younger guy (as in 17, I'm 28) in town who has a restored '72 Duster (he is a member on here, @John_Lemon ) and his windows are rock-solid; he said his wobbled just like mine until he installed new felt/rubber cat whisker seals. I think I will order a set of those, any recommendations for sources? I like Jim's Parts they seem to have the widest selection of parts and have been in business for the longest of the resto companies I've looked at, but a set of cat whiskers from them requires 2-3 week lead time. I see Classic Industries also has them, as well as Dante's Parts. Do they all come from the same source/company? I may also just call up Jim's or Dante's and see what they say. It seems like having the correct cat whiskers is crucial in keeping the windows stable, a few years back I put some felt-only ones in but they didn't really hold the windows at all and didn't help the problem (they were from an auto upholstery/trim shop, not specific to the car).

Also I read through @TrailBeast 's post a couple more times to understand what he did, I don't think I need to replace any rollers but definitely need new up-stop thingies (plastic pieces that go through the glass) and the rubber on the up-stop brackets in the doors has deteriorated and fallen off. I'm not sure if one of the complete door glass hardware kits are needed ($70 off Dante's not exactly cheap) but it might be a good idea just to take care of the whole shebang.
