Torsion bars lift or lower

Thanks....I’ve built a lot of cars jeeps trucks rock crawlers etc....so I don’t mind fab work....I just wondered if anyone else had done it already to get an idea
There was a guy who did it with a 74 Dart Swinger a few years back on here. It’s been listed for sale off and on since as it was nearly unsafe to drive or so he said. Getting steering geometry correct and safe to drive is a challenge for most
