The day after the bar broke I already decided to order a pair of 1.12" bars from Firmfeel.
But since they were in backorder at the time I still haven't seen them.

My Dart still has the SB and I recently upgraded to an alum 4bbl intake from the castiron 2bbl intake.
But I still want to add some reinforcements like innerfender and radiator support braces and front/rear torqueboxes to firm up the body a bit more.
