Such an issue with aftermarket door seals. I am baffled by the ease of new cars closing with new weatherstrip and yet the aftermarket seals are often hard and do not work. Huge issue I have with many restorations. Right now struggling with my 1969 VW Bus. Same scenario, doors close and sit real nice with no weatherstrip. Install the seal and you cannot close without slamming and it sits out too far. Ugh!
