As many of you know, Buick began the 1939 model year with a stub frame on the Specials and Centurys. Most of the car body behind the rear axle was supported simply by the bumper brackets. This turned out to by a poor system and Buick shifted to a full frame later in the '39 production run. HERE IS MY QUESTION: Does anybody know anything about a stub frame reinforcement "kit" that was offered by Buick for dealers to strenghen the existing early '39 Special and Century stub frames? Thanks for any help. Best, John in Wisconsin
