Door window weatherstripping kit

[72LSLB]

I'm going to replace all of my 72 c10 lwb door window and vent weather-stripping, felt etc; was going to purchase from LMC; are their kits ok quality wise or should I be looking at another vendor? Also; the drivers side window has to be messed with to get it to come down from the most upward position, it gets hung up; is that a regulator issue or is there something else I can adjust? Thanks!
