Re: 72 CJ suspension options?
I wouldn't sat that it is THE way to go, but it's an option. It all depends on what you want from your suspension. Wrangler springs are longer and as you know wider than your '72 springs. This means that they will ride better without sacrificing spring rate. What you're up against with this conversion is some fabrication (welding and cutting) to mount the spring and shackle mounts and a lot of very careful measuring to get the locations right. If that's not a problem for you I would definitely go that route.
