Weatherstrip questions 62' c10

[Bullett]

Ok, I have been looking to buy all new weatherstripping for my truck, I was thinking of the precision brand that people on this site have recommended. I was going to order it through jc whitney but their part descriptions are so poor, can't really figure out if I'm ordering exactly what I need. Does anyone have a good place to order good quality kits at reasonable prices? At this point, I am looking for the vent window kits and all the door window glass weatherstripping, inside and out and all the glass run channel? Has anyone bought the whole complete kit from Jc Whitney, it even has the windshield and rear window seals as well? I guess my question is, does this complete kit (part # 481978) have every door window and vent window weatherstrip/seals that I need. Also, looking at my doors, there are no weather strips on the doors at all that seal the door to the cab, just the seal that runs the perimeter of the door opening on the cab. Should the doors have some type of seals on them? I can't see any place or provisions on the doors that would suggest there should be seals.
