For my SOA I ended up using stock 1979 front Cherokee Chief springs in the rear of my CJ5 (free off junker headed to scrapyard). I currently do not have an anti-wrap device installed. No spring wrap observed. I've gotten by for more than a year wheeling like this. I'll keep on with current set-up till it becomes a problem, if ever. It's working good and I'm happy with it.
