All else fails , Chad had cut and welded the ones on the yellow race car , not pretty but he shortened them a little as well. Painted up they look fine.

I can only speak of the USA manufactured items made of hardened steel. I should think welding hardened steel would adversely effect the bar making it weaker if one failed to re-harden.

Don't disagree Robert but the limited welding at the ends would not really effect the bars ability to work. These have done many years hard work.

Robert is right, but so is Shaun.

Heating with a torch may cause breakage but often won't, but it also won't give you the correct hardness and stiffness values. You may take a bar that was good except for fitment issues and turn it into a bar that fits but has half the torsional stiffness it had before, because it isn't properly heat treated.

The good manufacturers do a two stage quench and temper procedure - see https://www.onallcylinders.com/2013/04/15/sway-bar-tech-heat-treating-and-why-its-important/

Many bars are modified with welded ends to give crude adjustment holes . Others remount the front attachments.
The torsion bars I make go through a number of processes before being ready for the car.

Be aware if you shorten the arms you increase the stiffness of the bar considerably.

If you weld the bar do it in a number of small runs and let cool for 2-3hrs each time .
