Hope ya find what you need Oscar.....
Hope I'm not jacking your thread but I had a similar problem a while back (see
handlebar-weld-issue) and luckily Big Dog was still around and stepped up to cover it.....they sent me replacement handlebars that were bent pipe rather than welded.....a design change for the better I suspect and one to consider perhaps if you decide to go the repair route....
Original welded design
Replacement Bent Pipe design
