There are pop rivets with shoulders available now that you can rivet on and they still leave the clip removable. Since they have a shoulder that sets tight to the metal they also seal better than the 1/8th rivets that you used to have to use. We have some on hand at work, but I don't remember who makes them. If I remember, I'll take a look tomorrow. I know that to install them correctly the rear glass should be removed if it isn't already.
I always thought the studs were installed on all the cars with or without the V/T, but I must be incorrect.
Good luck.
