I am replacing the weather strip around the corner windows on my 52 Chev pick up. I had to really struggle getting the windows back in place in the new weather strip and they don't seem very well secured from popping back out. Worse yet I can not see any way I can install the chrome bead that goes in the weather strip. Can someone share the procedure for installing corner windows and the center bead. I have two different installation tools sent from Brothers where I bought the weather striping.
