looking for some help in assembling headlihgts on my 30 chev.I have installed the new cork gasket from filling station (pressed into the edge of the reflector)assembled the unit ,tightened up the interior ring that holds the lens and reflector, but the outer chrome ring does not seem tight eneogh on the headlight bucket and there does not apear to be any way of tightening it. I am afraid the whole thing would fall apart driven this way. thanks
