I found a simple (read-cheap) rear bar solution for my '69 144S by fitting a bar from a 240 series. With a few washer/spacers between the bar and the trailing arms - and distance pieces inside the arms, the bars are solidly mounted and the pass through bolts serve the dual purpose of stiffening the trailing arms. For my purposes a 25mm Volvo competition front bar (gift from an ex-ITB racer) and a 240 19mm bar in the rear work just fine. -- Dave
