Wet Carpet

Rained the last few days and again I have a wet carpet. I was watching where it wight be leaking and I’ve come to the conclusion it’s the corners of the window gasket. It’s a 66 Valiant Signant. I replaced the gasket last spring thinking that would cure the problem. I guess it didnt. Wondering if the glass shop can shoot some sealant up under the gasket?
I had the same problem with my 70 Dart. New gasket, and sealant, but it would still leak a small amount in the bottom corner of the driver's side if I was driving it in rain. I added more sealant to that area and it seemed to stop.
