I did the same thing, drilling a couple holes in my door frame to get out all of the rivets. I don't feel it is necessary to use screws for the window as it will not be changed very often.

It's not about the need to change the window, it's about fastening tension.
With screws and a window you control the clamping force.
With rivets, you hope for the best and pray for no cracks.
Use screws.

I used the little thin nylon washers under the rivets & drilled the holes slightly over size & have had no problems. Dutch
