Remove inner door panel, unscrew large Phillips head screw that is in-line with the handle shaft(don't let handle fall), pick out old gasket.  "Install in reverse order".

Have fun.

Time to put a new weather gasket/bezel on the door handle of my '88 GL.
Took a cursory look at it today. Thought I'd better ask. How do you get the
bloody thing off to install the bezel on the handle shaft?

Thanks,

John
