LaSalle was a short lived, but beautifully styled brand of the GM Cadillac division. With a life span of less than 2 decades, this separate moniker was produced with manufacturing efficiencies incorporated in the design, with still popular details, to fill a gap in the GM Cadillac product line. We offer replacement convertible tops for their 1939 and 1940 2 door convertible coupe Series 50 and 52 automobiles. We have multiple fabric options and colors, plus the option to reuse your original window or purchase a new convertible top with a zippered plastic window.
