One last go at roof rail seals

The roof rail seals for my '72 Duster are in, and the fit seems very good. These are from Steele.
A few posts up folks were mentioning gluing them in. Is this necessary? I don't remember or have any evidence the originals were glued in.

On a side note, when I ordered the parts from Steele, the rear quarter window seals were on backorder. They told me that they didn't actually produce those!
