Ed, this rack is a solid fiberglass molding that rises from the front of
the roof and continues back to mate with the pop top.  It has a cavity
several inches deep that holds luggage.  It's attached to the roof by bolts
in the rear and four fairly light metal straps that are welded to the roof
in the dead space inside the molding.  The rack attaches to these straps
with screws.  It has a trim strip around the bottom edge to keep the raw
fiberglass off the roof.

My suspicion is that the straps could be bent slightly to shorten them --
but it could take some experimenting to get everything lined up right.
