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

yeah thats what freaks me out... sunday i was under that side getting the block numbers if it had broken while i was under.....i woulda been pinned....if not worse... ill send you pics and you can tell me if the break looks like your break,,,
