CAMARO2NV-----I searched far and wide and the picture that you've posted is the only one I can seem to find over the web as well. And he's right it only ties the two together. Who drives wit the window down in the rain?
Weatherstripping takes care of the water. In the photo???, you must have cut the entire rdrip rail out in order to a) shape the rod, and b) insert the rod to be welded, so how did you clamp the structure together or keep the seams close enough to be welded? Did the roof hold its shape enough along the edges that you could spot weld along the length of the rod?
