I am getting water in my '85. It seems I read years ago about this being a common problem?

get inside the vehicle and have someone spray high pressure water all around your windows,doors and windshield. It will show up, mark the locations, remove the trim and use flowable silcone to fix the windshield or back glass after removing the old sealant in the bad area. If it is the doors replace inner and outer door seals and fuzzies.

A good place to start in trying to identify find the problem is... tell us where it's leaking. :?
