After studying these photos, esp the red '66 original carpet, I'm wondering about a couple of things. I agree the factory process does a good job of hiding the bolt heads/stud nuts that secure the seat tracks, but wondering how you ever get access to the bolts/nuts to install the seat track. Do these slits in the carpet allow you to fold the carpet to one side enough to expose the stud or threaded hole in the floor pan, attach the bolt/nut, then lay the carpet back down over the bolt/nut once they are tightened? Or, should you install the seat tracks first and then attach the seats to the tracks in order to have more access to the seat track fasteners?

There is an interesting link on the Jeff Lilly Restoration site showing carpet install on a '66 442. There are some useful tips/photos shown. (Every other site I found had pretty generic instructions and/or instructions for carpet install in newer cars.)

The last photo shows them cutting small slits for the seat track studs to protrude up through the floor, which seems to indicate they just bolt the seat track down on top of the carpet, which seems surprising given their reputation for exacting restorations. Was this the way Oldsmobile did this?
