BUDDY P...
On a 28-29 Tudor, as with the 28-29 Coupe's, the "rivets" must be removed from the right and left front piller Assembly "door" posts.
The windlace, I think, for which is to be installed, "should" have a piece of thin cardboard sewed into the windlace itself so it can fit within the channel of the two pieces removed from the piller assembly posts. Then re-riveted to the piller assembly as was taken off.
It is the only way and the easiest. Of coarse you will have to remove a few things first to get to the tube-end of each rivet.
JW HASH...I believe you are referring to the 30-31 doors???...not sure on that one? There is no windlace on the 28-29 Tudor and Coupe doors.
