Replacing Vent Window Seals on a '67 F250:

[67FordTruckMan]

Any one out there who might have some advice in replacing the vent window seals for a '67 F250? The key problem has
been in finding/locating the shoulder rivets (5 per each vent window). I'm reluctant to take off the 47 year old seals
without having a new set of shoulder rivets in hand. I do have a set of new "Precision" seals, but holding off until
I can secure the shoulder rivets that are riveted into the division bar when it is removed from the vehicle's door.
Size matters, but without knowing the exact shoulder rivet size (diameter, length, etc.), it is difficult. Thanks.
