Door Window Glass

["Jim" <jimsnell@qwest.net>]

I was wondering if there were any differences in the door window glass from
year to year.  The door glass on my car doesn't come all the way up to meet
the convertible top on the rear part of the door and leaves about a 1/2 inch
gap.  The glass is all the way rolled up as it meets the top of the wing and
top at the front of the door.  Just seems like the glass is somewhat the wrong
shape and should rise a little higher on the back side.  Thoughts?
