Yes they went in after the top.

I dont know if I agree with this statement.
Original window louvered vinyl top cars I have seen had the top installed after the rivets.
Here's a picture of a patch of vinyl I removed and kept from a parted window louvered Challenger over 25 years ago clearly showing the top was installed over the rivets.
