I've never seen a kit for everything. However you can go on ebay and find kits with door seals, roof rail seal and trunk seal. Good luck trying to find quarter window seals.
I just realized that all those are out of stock (quarter window rubber) after you mentioned that. Why are manufacturers not keeping up with parts for 73+.dusters? They made a ton of 1973 and 1974 dusters. If i recall those were the highest production years. I just ran into this problem with seat foam for my 73+ bucket seats
