t top and door weatherseals

[usaf1313]

i just got an 85 gt. i was wondering if anyone on here knew where i could get a full weatherstrip and seal kit for this car? i need t top seals window to door, door to body, and the rubber piece at the front corner of the windows near the mirrors? i looked at late model resto and the kits for my car are extremely pricy or they dont have them at all. i also need to know what i would need to make the windows not so flexible when the door is open. i believe the guts for the doors and door panels are from a 90's model fox. any help would be greatly appreciated.
