I redid my door seals just 6 months ago. I received "T" clips with the replacement seals. My new rubber did not come with premanufacture d holes for clip insert. A member here suggested I use a soldering gun to melt holes where needed. I worked well.
Install rubber and hold in place with tape. Bend back the rubber to make new hole adjacent to intended receipt hole in door frame. When I removed the old seals there was some glue at the sharp turn but was dry every where else.
My seals seem to fit well yet leak a little air. I am going to remove it and add glue all around. I also found that the new clips did not hold as well as the original clips so I reused them.
I believe you may not have clips. I would try Rockauto of Original Parts Group. No one has pinto parts but most fords of that vintage are the same.
Good luck
Bill
