This subject has been hashed out a couple of times, and I have stated
that Older Chevy Pickups, Mack trucks, and Vanagons,among others, use
the moulding for lockers on the glass rubber channel.
Now let me say this again; some guys are lucky, when they take out the
old, weather beaten, chrome, and replace it with nothing, and their
glass dosn't leak, and some folk's are not.
I replaced mine with new, it gave my Van a face lift, and my glass
doesn't leak.
What more can I say?
