Our convertible top windows are manufactured from 6061T6
billet aluminum and consist of an inner and outer frame that are
held together with machine screws on the back. The outside frame
is available in a brushed finish or chromed plated (as pictured)
and the inside frame is brushed.   The outside dimensions of
the frame  are 23 1/2"L X 6 7/8"W. These windows are
absolutely beautiful and there is nothing else like them
available anywhere.  The quality is second to none.
