broken torsion bar? what to replace with and how fun is it to do?

I had one explode just sitting in the yard 440/727 combo in place of the swapped in 318
So I had to raise front end by tightening the adjuster and it snapped a few weeks later.
Turns out the PO had removed the front suspension to rob the sway bar LCAs and swapped the bars side to side
Causing it to break radially
